Even if a solid 20% of your day is still dedicated to Angry Birds, you’ll definitely feel like an adult at The Petersham. This restaurant inside Covent Garden outpost of Petersham Nurseries serves up modern European food like white truffle tagliatelle, sea bream tartare and partridge risotto. In case the food didn’t give it away, you should know that this place can get pretty expensive, but their three course pre-theatre menu is only £30.50. If you’ve got a thing for blown glass and chandeliers (who doesn’t), sit inside, but if you want to take in the very idyllic floral courtyard, you can sit outside too.
