I'm heading to Spain in a week and a half and have been trying to do some research on where to eat, but am still unsure. I'm travelling with my boyfriend and we like pretty much all food. We would like to keep most meals reasonably priced (~$100 for both of us), and maybe 2-3 nicer meals. Does this seem possible? We would like to go to places with a fun atmosphere (we're in our mid-20s) but the quality of the food is more important to us. The other thing is that we will be in Barcelona Friday - Sunday, which restaurants are open on Sunday night? If anyone has some recommendations in any of these cities I would greatly appreciate it. Restaurant addresses would be helpful too! Thanks.
