Fried fish
Without a doubt, it’s one of my favorite places. When I go to Cadiz, I always go to Romerijo to eat their seafood. It’s located right in the Port of Saint Mary. It’s one of the places I recommend to people traveling to Cadiz, as it has a good price-quality relation.
You can get there, sit down, ask for a menu, there’s a large variety of seafood options to choose from at distinct prices. I think the best thing to do is find a table and then head over and select the type of seafood and amount (weight) you want. You can then enjoy some beers or a nice wine with the meal.
If you want to try to shrimp omelet, you should ask for them as a tapa (appetizer), ½ portion or portion.
