Gate-side drinks only at GUM’s Main Terminal bar
By the time you reach the Main Terminal departures area at Antonio B. Won Pat International Airport, Drinx Bar is basically the only proper bar option in sight. The setup is simple: counter service, a few stools, and standing room that spills into the concourse near the gates. It feels more like a kiosk than a lounge, but if you want a beer before a United or Japan Airlines flight, this is where you land.
Opening hours track roughly with the bank of late-night and early-morning flights, so Drinx Bar tends to be open whenever the international side of GUM is busy. Don’t count on a posted schedule; the safest assumption is that it opens a couple of hours before the first departures wave and closes after the last. If you’ve got a 01:30 departure, check it on your way to the gate rather than planning a visit later.
Pricing lines up with small-island airport expectations: think around $7–$9 for a standard bottled beer and well over $10 for mixed drinks, depending on brand and pour size. Food is minimal or non-existent, so treat this as a liquids-only stop and grab something solid at the Main Terminal landside before clearing security. With a 2-star overall rating, expectations should sit firmly at “it’s here and it pours alcohol” rather than anything special.
Drinx Bar sits airside in the departures area, so you must clear security in the Main Terminal first; you won’t find it landside with the check-in counters. There’s no cocktail list worth studying, and nothing on the menu is famous enough to chase. Order something simple like a local beer or a basic highball and skip anything that sounds complicated or custom.
Tip: if you care about seating, show up 30–40 minutes before boarding, grab one of the few stools, and keep your boarding pass handy since staff sometimes double-check departure times.
