Here are some mouth-watering suggestions of dishes to eat and restaurants where to eat them in Madrid. Every month El Mundo, one of Spain's foremost newspapers, puts a selection of restaurants where you can eat a certain type of dish on to its Metrópoli section. Here are a list of recent additions to its Top Metrópoli section:
Pasta con Marisco - Quite simply Pasta with shellfish!
Terrinas marineras - Seafood terrines
Lasaña creativa -Don't think this needs a translation. A good selection here of 11 restaurants.
Espaguetis boloñesa - Sticking with the Italian theme another fine selection of restaurants to eat this Italian dish
Bonito - a delicious fish from the tuna family. Very popular in Spain.
Mero - this fish is apparently called Grouper Fish in English and can often be found in fish markets in Spain
Sopa de pescado tradicional - Traditional fish soup - made with a good selection of fish.
Sopas exóticas de pescado - Here's a selection of Far Eastern restaurants offering "exotic" fish soup.
Platos con chucrut - once more stepping out if Spain here we have a selection of restaurants that serve Sauerkraut. A personal recommendation on this list would be Edelweiss.
Goxua - let's finish off this selection with a dessert. Goxua is a
Galician Basque (oh bugger! I got this completely wrong thanks Paloma) dish generally made of sponge, cream and liquid caramel. Correct me if I'm wrong!
