Koi Ramen Bar
Tonkotsu. Small counter, Tokyo style, in Tooting · 432 reviews on Google
It's a small place run by a Japanese team, with the vibe of a Tokyo street counter. The space is very tight (few seats), which can be an issue for larger groups.
Rich, hearty tonkotsu broth, with extremely tender pork and noodles praised as some of the best in London, at a tiny counter inside Tooting Market.

The pork tonkotsu was fantastic — perfect noodles, egg and meat, definitely the best ramen I've had in the UK.
-
Best ramen in south London, maybe all of London — consistent, homemade excellence.
-
It feels like sitting at a tiny bar on a street in Japan, and you should always ask for all the free toppings.
-
Deep, comforting broth and exceptionally tender, slow-cooked pork that melts with every bite.
-
Both are great, but the Shoyu stands out for me, and the gyoza is a game changer.
-
One of the best I've had, including several visits to Tokyo — and the matcha ice cream is a real treat.
-
We ordered the Pure White Tonkotsu and the Naked Ramen; both were authentic and delicious, the broth rich and creamy.
-
Authentic Japanese ramen made with care by Japanese staff — really good.
-
The pork belly ramen is to die for; I could eat here every day.
-
They offer kaedama too, and even sorting out a rush of takeaway orders they served us quickly, with a smile.
Before you go
Very small space (few seats, inside the market) — may not be ideal for large groups or very busy days.
