For people interested in eating at fermentation-focused modern restaurants -
- Noma is the obvious (expensive) choice and the author of an eponymous fermentation book.
- Silo in London is a lesser-known restaurant that does a lot of in-house lacto fermentation and garums
If you have any other to add, please to comment.
(I specify "modern" because a lot of traditional cuisines incorporate fermentation, such as kimchi, sauerkraut or even koji in soy sauce)
