Bodega 18 on Old Bridge Street is everything you want a tapas place to be: friendly, lively, and packed with an amazing choice of dishes. The food is authentically Spanish, drawing on family recipes as well as everyone's tapas favourites (yes, they do serve patatas bravas).
Look out for the daily specials, and if you've any room left, don't miss the puddings. Combine the delicious dishes with the excellent wine list, and this really is a great place for an evening out. They're also open for lunch - look out for the three dishes for £15 offer.
If you've tickets at the theatre, Bodega 18 offers a pre-theatre service with a special menu. The restaurant closes on Sunday; however, if you really need your tapas fix, their sister restaurant in Falmouth is open all weekend.
