A group of friends are making our first trip to Barcelona in late July. While we expect to spend most of our days in Barcelona, we are actually staying in a villa just outside of Sitges. Although I can find lots of good advice here for Barcelona, I'm wondeirng if anyone has any restaurant recommendations for Sitges? Also, our villa has a barbecue and I'm wondering if there are any suggestions for places to buy fresh fish, seafood, etc. that we can cook ourselves?
