I've had dinner here several times in past few months and each time the food was marvellous and the restaurant's atmosphere distinctly Spanish.This includes service so be warned. Personally I love it, it's a little bit of real Spain on English ground and I feel here most relaxed. But if you're looking for a quickly delivered meal and perky waiters - stay away! La Paella and its staff are laid back, proud and worth the wait (and money).
For tapas, If you like seafood try their Pulpo a la Gallega (octopus in paprica and olive oil) and , for vegetarians Espinacas con Almendras (spinach with almonds) are a must! http://www.lapaellatapasbar.com/
