Hi - I live in London and know lots of restaurants but I'm looking for something quite specific for a special occasion meal which is a really nice restaurant (for me, DH, one teen, one tween). Happy to consider all sorts of cuisine, but what I care about most is the vibe. So needs to feel special and treaty but not unbearably cool and/or noisy and/or dark. So many good restaurants are one or all of these things now. I also don't want silent/unbearably stuffy and starched white tablecloths either. But just nice and relatively laid back, a bit special and not too loud or dark and small-platesy. Any ideas?
