We went to El Rincon, a long time business in Adams Morgan - I believe about 35 years, for dinner and drinks.
The place was only half full but the atmosphere very authentic. Somewhere south.
The Appetizers were great, especial the Spanish Chorizo, and the entrees were ok. Large and filling, very tradition. Enjoy bottle beer for drinks.
The waitress Extasis was lots of fun, right on with everything we need, and sincere.
Overall a great visit, recommend it highly. Feels very local, neighborhood, hang out - ish!
