Review: We went twice to Idiot which served fish dishes and a range of vegetarian versions of Russian dishes. First time had the borsch and perogis and the second time had a delicious pear salad and the perogis again! The building is by a canal, about 5 mins from ST Isaac's church and the interior is really cosy and friendly. The staff spoke English and the menus were in Russian and English and the prices weren't too bad for Russia! Food is served with a wide, complimentary selection of breads which were lovely.
