This restaurant, I understand, used to be inside the Mercado Central - but now is across the street (Avenida 1) to the north. It's worth the search. The fish soup is excellent, and their hamburgers/cheeseburgers aren't bad either. Ate here a few times.

In the middle of San Jose, it is delicious, the fish soup could wake a dead man and the sea food platter never disappoints. The service is fast and not always super friendly, just make sure they write down your order.

I had read the reviews so as we were shopping at the butcher next door we went in for lunch. Super, friendly staff, nice atmosphere with a couple of regulars enjoying their fish soup over the newspaper. We both ordered fish...one plain, one with garlic sauce. The latter was beautifully cooked - couldn't have been better - but the former... More

The title says it all - some of the best ceviche I've ever had - fresh, flavorable and generous portions. Very friendly and helpful staff. I'm a beginner Spanish speaker and really had fun with the waitress trying to order Saltine crackers to go with the ceviche (galletas Soda for future reference). As mentioned in other review, it's not easy... More

We ate there several times on our visit and were not disappointed at all! The ceviche is excellent and my wife liked it so much that they kindly supplied her with their own recipe to... More

This great little gem of a place is off the beaten path. I have had two dinners there about a year apart. Thanks to my Tico friends for making Mariscos Poseidon a stop whenever I am in San Jose. Start off with their Peruvian style cerviche then move into any of their complete menu of seafood. They close about 6... More
