On the Border COEX City Airport occupies the ground floor of the Korea City Airport Terminal in Samsung-dong, Gangnam-gu, Seoul, and is one of the larger locations in the Tex-Mex grill franchise that traces its Korean presence back to an Apgujeong flagship in 2007. The menu faithfully covers Tex-Mex fundamentals — tacos, burritos, fajitas — with unlimited nacho refills as a standout perk. Ordering a party set delivers a spread of tacos, burritos, and fajitas in one go for variety. The steak salad is a popular choice, and portions across the menu run generously large. The spacious family-restaurant layout accommodates large families, group gatherings, dates, and casual meals equally well. Beer promotions run frequently, making the restaurant a convenient spot for a drink alongside food. Menu composition matters: stacking too many similar-tasting dishes leads to heaviness and palate fatigue, so balancing spicy and mild selections is the better strategy. The quesadilla draws mixed feedback, and steak occasionally arrives overcooked, so confirming doneness at the time of order is prudent. Staff are generally courteous, though during peak hours the volume of diners can slow down additional orders and drink delivery. Prices sit on the higher side, but discount cards and Shinsegae gift certificates apply and meaningfully offset the cost. COEX parking validation is available — two hours free above a certain spending threshold — and the Starfield Library is close enough for a pre- or post-meal visit.
