El Paso Cafe is an institution in the Buckingham neighborhood. Just south of the Glebe/Pershing intersection, it is known for its authentic food and atmosphere. The wait staff is attentive and efficient, weaving between tables packed close together to accommodate the large parties that frequent the cafe, especially on weekends. I always get one of the soups, beef or chicken, full of corn on the cob, lettuce, yucca, other vegetables and whole pieces of chicken or large slabs of beef. Others prefer the fish tacos, or other excellent renditions of traditional Mexican fare. Although another reviewer complained about the music, I thoroughly enjoyed the great Mariachi band. They, too, are the real thing. Although they sound loud--trumpets, etc in a very small space--they are terrific and there is plenty of time between numbers to get in some normal-level conversation, and talk is not impossible even when they are playing. Another reviewer complained about the service, but our large group of 14 children and adults had excellent service on a very busy night on our recent visit. And I agree with "Soren Trips:" the margaritas are delicious.
