I found Salvador & Amanda through an offer on After Work Deals - we got a free jug of Sangria between a group of four of us whilst having dinner, it definitely made a great start to the night.
My first impression was surprise, I'd walked past S&A loads of times before and I had no idea that there was such a large venue underground. It's well decorated in a fairly typical tapas restaurant style, and there's a real buzz about the place.
Service was really fast and friendly, and they made some great recommendations from their tapas menu. On the whole, the food was very good although it was a bit on the expensive side and I certainly couldn't describe the portions as generous! And the After Work Deals offer certainly helped manage the cost. Nonetheless, for the overall atmosphere I would still recommend Salvador & Amanda.
