Outright one of the best if not THE best tapa restaurant in London. The daily specials are often better than the regular menu so I highly recommend them. No reservations are taken so be there early and limit your waiting time to less than half hour. Show up later than 7:30pm and expect a long wait. Once I was in the queue for 80 minutes but it was all worth it. Try some ham while you are waiting. You would actually pay less for them, in particular the lomo, than you would in Madrid. Some would consider this restaurant pricy but you get what you pay for, and much, much more. Absolutely my favorite, not just Spanish, but of all restaurants in London. They have a sister restaurant called Fina that takes reservation. Don’t bother. It’s not as good. You have to queue for the best.
