Gate 4 in Terminal A means Gastro Pub is your main sit-down option
Right by Gate 4 in Terminal A, Gastro Pub is the standard airside bar/restaurant at SJO for anyone already through security. It runs from 5:00 a.m. to 7:30 p.m., so it covers most early US and Canada departures plus afternoon Europe traffic. Sign says café and bar, but this is a full menu spot, not just snacks.
Expect $18–$25 USD for burgers and pub plates, which lines up with reviews calling out “$20+ for basic bar food.” Pricing sits at or above tourist restaurants in upscale San José neighborhoods, so budget for a full city dinner bill, not a cheap airport bite. This is squarely a $$ option, despite the casual look.
Menu runs classic bar food: burgers, fries, maybe wings, plus beers and mixed drinks at typical airport markups. Travelers say the food quality is “fine,” not a disaster and not special, and the spot averages around a 5/10 vibe for value once you factor in the airport premium. Order here if you care more about having a real table near Gate 4 than hunting for something cheaper in Terminal A.
Service is the main pain point. Multiple reviews mention 30+ minute waits for cooked-to-order dishes during mid‑day and evening departure banks, especially when North America flights are boarding off nearby gates. If the seating area looks packed when you walk past, assume your burger and fries will not be fast.
Regulars with lounge access say they only sit down at Gastro Pub when their lounge is full, closed, or they’ve got a long delay. Others try to eat in San José before heading to the airport, then just grab a drink at the bar here. A few note that checking the room from the entrance saves them getting stuck after ordering.
Tip: If you see a line of more than 4–5 tables waiting to pay or flagging servers, skip hot food and stick to a drink and maybe fries so you don’t cut it close for boarding at Gate 4.
