Thank you, Flo, for the answer, I'll try those options.
Georgian food is amazing. Apparently the best place in London (someone was asking upthread) is Little Georgia in Islington. I tried going once but it was renovating so didn't actually eat there. But I got the book by the owner called Supra I often cook from. There is a bit of intersection of spices with Ottolenghi, like fenugreek, etc. They cook with lots with walnuts, coriander, pomegranates. It's generally amazing. And Georgian mineral water, Borjomi, is the best. Sometimes you can get it in Russian / Polish food shops in London.
There is a cafe nearer to me, The Georgian in Clapham Junction. It is not fine dining, but one can get some sense of the cuisine. Their khachapuris are good even if fatty a bit.
