If you're looking for a tapas place that is a bit off the beaten path and not quite as overrun as Jaleo (no offense to Jaleo - it's definitely one of my favorites!), Bambule gets my vote.
The sangria is strong and fruity. The tapas are a bit overpriced, but amazingly delicious. There's a decent selection, and the wait staff is attentive.
For dessert, try the profiteroles...it's like heaven on your plate....guaranteed happiness.
Also, my friends and I loved that there was a live band.
