Small, friendly spot for budget bifanas and creative empanadas; excellent for a quick bite, but portions and spice profiles divide opinion.
Union earns a solid grade B through strong food quality anchored by excellent bifana and attentive, warm service, though inconsistent empanada execution and cramped seating prevent higher standing. The charming sunlit window perch and exceptional value make it a worthwhile casual stop for Portuguese sandwiches, though it lacks the polish and reliability of grade A-grade establishments.
The tiny room opens to the lane with stools by a bright window, where the city hums by and staff greet you with warm, friendly energy. Diners describe the bifana as juicy and comforting, one calling it a trip highlight, while another praised the cheerful, sunlit perch for people-watching. Service feels personal and fast most of the time, though a few guests noted waits when the kitchen is busy. This kitchen leans traditional-but-house-tweaked: a bifana with tender pork and signature spiced sauces, plus empanadas that are more creative than canonical. Fans love the bold seasoning and value, while critics say portions can be small and the empanadas vary from superb to undercooked or too spicy. If you are after a quick, flavorful snack between sights, this approachable, counter-led spot fits nicely. Families do fine here thanks to simple sandwiches, cheese-forward empanadas, and friendly staff. Space is tight and tables small, but kids can share the two-sandwich bifana deal. Spice levels differ by filling, so ask for the milder picks to keep things kid-friendly.
