Named for the family recipes and traditions that have “streamed” together over the years, El Arroyo offers the ubiquitous Tex-Mex fare as well as a satisfying array of authentic Mexican dishes. We fell in love with the Rocha’s Ceviche, a lovely mix of shrimp, tilapia, onions, cilantro, tomatoes, and avocado, and it served as a lovely prelude to the Lupita Salad: tomatoes, mixed greens, cucumber, and oranges, with queso fresco and bacon. Our hands-down favorite, though, is the gorditas, masa pockets stuffed to overflowing with beef fajitas, onions, and queso fresco, served with charro beans and huitlacoche, a true delicacy. Our vegetarian friend was delighted with his Green Quesadilla: cheese stuffed with spinach, onions, tomatoes, squash, mushrooms, and zucchini.
