Fun restaurants for Christmas girly night out

[user1473602935]

Sorry to be mentioning the C word in August but I'm trying to be organised (plus gagging for a night out as 33 weeks pregnant!)

I'm very out of the loop with where to go in London these days...

I'm looking for a recommendation of a fun / lively nice place for dinner and drinks for a Christmas girly night out, nothing poncy or too pricey, ideally central or south

Any ideas?
