I'm a big fan of Spanish food, which is remarkably like British food in some ways (well, they have black pudding for one thing. And chips). So I visited La Movida in nearby Battersea, which is attracting favourable reviews on londoneating. I hardly ever go anywhere I haven't been before these days, so this was an event.
It's a fairly traditional style restaurant, and even on a Friday evening very quiet. However the food - starters and tapas - was good, very good in fact - if you go order at least two portions of the spicy broccolli, which even my broccolli-hating son loved. And an excellent fiery chorizo. The desert menu was of the "Hawaiian Surprise" variety, but with a few home cooked specials (I had a very nice crepe). Can't remember what the bill was except that it was very reasonable. Unfortunately La Movida isn't near any major transport hub (Clapham Junction is nearest, about 15-20 minutes walk away, and frequent buses). It deserves a wider clientele, however.
Oh, and on the Iberian front, I've also been to Silva's, a Portuguese restaurant in Hampstead, a few times. Very traditional Portuguese food - you don't really need a menu - but good; the starched napery is attractive, and the service more or less perfect. And the Zimbro 2005 Red is an absolute corker. Pop in after an invigorating walk on the Heath.
