Zarzuela de Mariscos is a typical Catalan dish; it is, roughly speaking,
paella without the rice. I always forget about Coobah, which has been going strong for years. I'm a sucker for seafood soups and almost always order it when it's on the menu. My favorites are at neighborhood Latino places. They tend to understand these soups best and provide a great value. My top options include Cuban spots (Habana Libre makes a nice
sopa de mariscos), Mexican marisquerias (Veneno's
siete mares is a stellar example), and Ecuadorian/Peruvian (Machu Picchu's
parihuela is excellent).
