I couldn't find anything on this restaurant here on the board so here is my review.
Sol de Espana is located on Rockville Pike across from the Wintergreen Shopping Center (which has a great Thai restaurant, Benjarong in it) just south of Rt. 28.
Pretty room, white table cloths, friendly service, and great food. We started with appetizers, which were excellent if small. My son had the Calamares Fritos, light, cooked perfectly and served simply with lemon. My wife had Pimientos Asados, roasted sweet peppers with garlic. I had three wonderful grilled sardines, crispy skin with perfectly flaky flesh, also served simply with lemon.
For entrees the boy had a half lobster with scallops and shrimp in a delightful and light tomato based sauce. My wife had Rape Catalana, monk fish, mussels, and shrimp in a frest tomato, saffron, garlic and brandy sauce. I had soft shell crabs in garlic sauce. All were excellent, with the nod for best to the Rape Catalan.
We washed it down with a bottle of Marques de Caceres, Rioja 2003. Dry and crisp, with just the right amount of acidity, bright melon flavors with notes of lemon and lime and vanilla from oak. It was clean and fresh and complemented the food perfectly. Wine glasses unfortunately were the small round bowl type, but we made do.
The wine list is large for a Montgomery County restaurant, running about 12 pages. Only complaint, no vintage dates except on the last two pages, the reserve wines. Prices however are very reasonable with lots of choices in the $25-30 range, both red and white.
Dinner ended with desserts; orange bread pudding and coffee for me, a moist and huge rasberry cake with a latte for my wife, and a wonderfully creamy and rich cheesecake and expresso for my son. They make great coffee and expresso btw.
Dinner, wine, tax and tip was about $160 for the three of us. We have been back several times and enjoyed it very much each time.
