yeah the russian place i've been to was further up kingsland road, more dalston than shoreditch. only been there a couple of times, for birthday parties, was very fun both times but i can't comment on what a usual night there is like.
and speaking about lebanese restaurants, me and my girlfriend went to this place called Levant recently and it was fucking sweet, tucked away down a little side street, amazing food, lovely vibe, not as expensive as the reviews make out (just get a load of mezzes in is the best option):
