"A prolific Alexandria restaurant group just unveiled a Mexican-themed patio perched on the boat-lined banks of the Potomac River in Old Town. An Airstream trailer nestled next to Alexandria’s iconic Torpedo Factory Art Center sells tacos, bowls, and starters such as street corn, salsa, and guacamole. Patrons can grab their orders at the trailer and take a seat on an adjoining 60-seat patio dotted with red and sea foam green chairs. Waterfront drinking calls for frozen margaritas that can be upgraded to passionfruit or mango. There’s also sangria, draft beers, and “High Noon” cocktails that mix vodka and soda with fruit juice (pineapple or ruby red grapefruit). Six types of tacos ($4 each) feature options like house chorizo and potatoes; pork belly and agave glazed pineapple; and chicken pipian with pickled apples and pumpkin seeds." - Tierney Plumb
