Review of Tacos El Pariente II (Gaithersburg)

Upon my delightful venture into Tacos El Pariente II, I was eager to savor some authentic Mexican flavors. The highlight of my visit was undoubtedly the good birria; each bite was bursting with tenderness and spiced to perfection. I was particularly fond of their spicy red salsa, which added a tantalizing kick that danced on my palate.

However, my enthusiasm was met with a dose of reality. The slow service left much to be desired, transforming my dinner into a bit of a waiting game. As I tapped my fingers on the table, I pondered the irony of how a bustling taco joint could keep hungry patrons in such suspense. To compound my disappointment, the food portion was lacking, leaving me wishing for just a tad more to satisfy my cravings.

Regrettably, my repeat visit didn’t live up to my high hopes. While the birria remained consistent, the service seemingly had taken a vacation. Overall, while Tacos El Pariente II has the potential to shine, it struggles with execution. I’d still recommend giving it a shot for that delicious birria, but prepare for a bit of a wait!
