my parents (early 50s) and their friends (also early 50s) want to go to a tapas bar/restaurant for the first time. this also on a saturday night, which might cause problems as far as reservations go. where would be a good place to take them? i was thinking of casa mono but thought it might be a little crazy for them. i'm looking for a place with really good food and wine, and the atmosphere doesn't really matter as much as the food. i've read reviews on tia pol, las ramblas and alta, but have never been to any of those places so if anyone could chime in, that'd be great. thanks in advance!
