My wife and I are heading to Madrid, Granada and Seville for a few weeks early this summer. We both are avid foodies and cooks. We like both simple eats, tapas, and haute cuisine. Can anyone recommend restaurants in any of these cities. Also, I have a severe allergy to shellfish (shrimp, lobster, crab), will this really inhibit my ability to eat in this region? Are there any other small towns that people would recommend going to for food and wine? Thanks.
