I can't believe Arpa got such low reviews! It's a little expensive, and you sometimes have to keep ordering, but the food is fantastic. One of the best things I've ever eaten is the goat cheese with honey. Who would have thought of mixing goat cheese and honey?
So if you're going to Arpa, be prepared to spend money and order everything you want in doubles. It's part of the fun of tapas.
The service and presentation is definitely fine-dining, although the atmosphere is a little more casual. I think it's a great place for girls' night out...like the kind of girls' night out where you're dressing up and pretending to be the Sex in the City chics...or for date night.
