This restaurant was recommended to us by a Latin American chef from another Annapolis restaurant. He said that Sin Fronteras has the best prepared Latin food. He was right. We have dined there several times and continue to go back. The first thing we noticed during our first visit was how friendly the restaurant is. We were welcomed at the door by the owner, Walter, who has a knack for making everyone feel welcome and at home. The second thing we noticed was how fresh the food is. The guacamole comes from fresh avocados and is made on site. Same for the tacos, and unlike most other establishments, the nachos are homemade with all natural ingredients. And the main courses are also fantastic. We continue to dine at Sin Fronteras because it is friendly and the food is great.
