The best place for a glass of wine*. It's the perfect balance – not too formal, not too informal either. Food is consistently good. Lamb's Conduit Street is a little oasis in the midst of Bloomsbury. (*slightly overpriced)
Camping in London? Absolutely! This is one of a few sites which has direct access to Epping Forest from the campsite. Easy to get to by tube, with a fire field and 50 acres to spread out in, this is a great place to recharge your batteries.
