As of October 2024 Filter Coffee House has changed its interior layout and so is now takeaway only.
Filter Coffee House, a tiny café on Castle Street offering authentic South Indian coffee, opened last August. It occupies a unit which as far as I can remember used to be home to a very small, rather unsuccessful produce store by the people behind Tamp Culture (remember them?). I found myself stopping in last year a couple of weeks after Filter Coffee House opened and, slightly bending my usual rule to wait a month, I talked about it on social media.
I couldn’t help it. I waxed lyrical on Instagram about their coffee and, in particular, their banana bun, a confection quite unlike anything I’d ever eaten before. Not quite sweet, not quite savoury but glazed, complex and moreish, it was not the kind of thing you eat and forget. Quite the contrary: you want to tell the world about it. I loved it so much that when I put together my list of Reading’s 50 best dishes last September, as part of the blog’s 10th birthday celebrations, I snuck it in at number 47. I called it a little miracle.
Maybe I was jumping the gun but I had a feeling it was going to be huge, and I wanted my admiration of that banana bun to be a matter of public record as soon as possible. Because there are few four word combinations in the English language quite as satisfying, if you ask me, as I told you so.
Anyway, the amount of praise that bun has garnered on social media since has borne out my hunch. But not only that, if you follow Filter Coffee House’s hugely winning Instagram feed you’ll see that they’ve really flourished in the last five months. The month after they opened they teamed up with nearby Rise to expand their range of baked goods. In October they introduced a menu of Saturday specials, and in November they brought in a sandwich menu.
In December, naturally, there was a Christmas menu – the “Mistle-Toast” is still available, if you’re tempted – and now Filter Coffee House also stocks goodies by Cocolico, Reading’s vegan pâtissière. The overall picture is one of constant forward movement and innovation, and it shows no signs of stopping: last Sunday, for the first time, they had a stall at Caversham’s Artisan Market.
And yet, shamefully, with one thing and another I had not been back since that first visit back in August. Of all the places I’d neglected in the latter half of 2023, sorting this one was right at the top of my list. So last Saturday, lured by that specials menu and fresh from the elation of having bought our wedding rings in town, Zoë and I sauntered over, keen to see how things had progressed.
It was definitely compact – on a par with the likes of Mama’s Way – but Filter Coffee House is really cosy and welcoming. Just the four stools, three of which are up at the window where you get a big, sturdy ledge for your food and drink and a view out on to Castle Street. The pastries were all on display under perspex with an interesting mix of the conventional stuff Rise does – the last surviving pain au chocolat looked very enticing – and the more unconventional.

It was only later that I discovered that the “masala bomb” was Filter Coffee House’s take on a vada pav, but with the whole roll stuffed with masala rather than a deep fried potato fritter: if I’d known I’d have ordered one. Prices are extremely competitive throughout – that banana bun costs £1.50, the masala bomb £2.50, sandwiches start at £4. And the sandwiches are an interesting bunch too – they’re not wild combinations, and they skew more European than some of the menu, but I was tempted by the Arabian Prince, with falafel and pickled onions. Maybe next time.
But I was there for the specials, because I’d seen them crop up on Filter Coffee House’s Instagram stories on several Saturday mornings and they always looked really appealing. The menu proudly proclaimed that they all cost less than a fiver, which if anything didn’t do them justice as none of them topped four quid. All were vegetarian, a few were vegan, all were tempting. Most were savoury but one, steamed rice cakes stuffed with jaggery, was sweet.
I asked how big each of the dishes was and was told they were on the small side, so we ordered two each of our favourites and took our seats up at the window. That was, as it turned out, an error because they were both very well proportioned for sharing and, next time, I’d probably order more singleton dishes rather than doubling up.
But never mind – the food was easily good enough to make said next time a “when” rather than an “if”. The first of those dishes was a couple of the now legendary banana buns with a little cup of sambar. The cooking takes place in the basement, and these came up about a quarter of an hour after we placed our order. Five minutes later, the second portion materialised.
Eating the banana buns in this context was interesting, like seeing an old friend in a new place. On their own, that time back in August, I was struck by the interplay between the sweet and the savoury – sometimes it feels like only European cuisine so rigidly separates the two – the banana on one hand and the speckling of cumin seeds on the other. All those things were still present and correct, the whole thing with a fantastic glazed exterior and a doughy inside, hot enough that you needed asbestos fingers and with just enough oiliness to leave you requiring a napkin.

But having them with the sambar transformed them, making them more out and out savoury. And the sambar was excellent: I’m used to having it in some places in Reading and finding it a little watery and bland. This looked like it might be too, but it packed a punch with dried chillies in the mix. Tearing and dipping the bun made for a potent, warming experience not quite replicated anywhere else in town. If I was being critical, ever so slightly, I might have liked more sambar (they do charge something like 20p for extra) but what I really wanted was a better vessel more suitable for dipping and teasing out the last of it than a tiny, flimsy paper cup.
The second dish also came out in two waves, about five minutes apart, and for me was even better. From the moment I saw goli baje, fritters, on the menu I knew I would order them when I visited, but they exceeded my high expectations. The epitome of cooked then and there, they were irregular, knobbly, piping hot spheres of dough – golden on the outside, again too hot to touch and completely addictive. They were like doughnuts, or like doughnuts would be if they were savoury, just airy enough and shot through with little chunks of green chili. Hot, in other words, with a brilliant level of spice which built and built.

But of course there was coconut chutney – cooling and fresh – to dab the fritters in, over and over again. If the banana buns were how Filter Coffee House broke into Reading’s food consciousness, this wonder of a dish gave a pretty clear sign that they intended to stay there. In this case, even though you could happily have shared a portion of these with someone, I was absolutely delighted to have them to myself. Zoë felt the same way, although the way she phrased it (“these are really fucking good”) was all her. Personally, I’ve half a mind to go back tomorrow and have them again, although that sandwich menu is also calling to me.
Our first drink, also from the specials menu, was equally outrageously good. Masala hot chocolate was just an awesome drink – indulgent, sweet but not too sweet, packed with ginger and cardamom. “If they stuck a slug of espresso in this it could give C.U.P.’s mocha a run for its money” was Zoë’s verdict. I could see what she meant, but I thought it was perfect just as it was. I didn’t realise until later that it was also completely vegan, having been made with soya milk. If I’d known, I might have turned my nose up at it, so I’m glad I missed that detail. Even if the dishes I ordered and the others I’ve talked about don’t float your boat, it’s worth going on a Saturday just to try this.
We got talking to the owners when we’d finished eating, and they told us that business had been pretty good since they opened in August. They’d been really lucky with word of mouth, they said, and they had quite a lot of custom from the magistrates court opposite. The owners were exactly as I would have expected from their social media – enormously engaging, friendly and passionate about what they were doing. And, as so often, I found myself thinking how lucky we are in Reading that people like this still set up businesses that bring so much to the town.
Hearing about people from the magistrates’ court coming in to order their coffee made me realise we’d been remiss in not trying it ourselves, so we ordered a couple of filter coffees with milk just for completeness’ sake. I really enjoyed mine – totally different from the standard latte you can get in many other places in Reading, with a certain condensed milk sweetness that felt more cafe con leche than flat white. Our two drinks apiece and two small plates each came to a total of twenty-seven pounds, which is a bargain and a half.
I wish I’d got to Filter Coffee House sooner, and that I’d reviewed it last year. But actually, everything has turned out for the best – partly because they have spent five months doing really impressive work making their business realise its potential, knitting it into the fabric of Reading’s food scene and offering something genuinely unique.
But also I’m glad I waited because this is a really fitting review with which to kick off 2024. The blog has always been about celebrating independent businesses and people who are passionate about adding something to Reading, helping to challenge our reputation as a town full of featureless chain restaurants. Around five years ago that reputation was deeply unfair, but in the last five years I’m afraid the scales have tipped. So it’s positively life affirming to see that we can still attract places like Filter Coffee House, and that the situation is far from hopeless. My last review of last year, of the deeply charming Minas Café, went a long way to restoring my faith. Filter Coffee House – small, plucky and brilliant – may well have finished the job.
