Near the Main Terminal gates, Pacific Coffee is your caffeine stop.
Pacific Coffee sits airside in the Main Terminal at Antonio B. Won Pat International Airport, and it’s one of the few branded coffee options past security. The shop focuses on standard espresso drinks and drip coffee, plus basic pastries and snacks. Expect menu boards in English with prices in US dollars, since GUM operates on USD across the airport.
The shop keeps airport-style hours, typically opening before early departures around 05:00 and staying open into the late-evening wave of flights. If you land on a red-eye that arrives after 23:00, don’t count on it being open. Seating is limited to a handful of small tables and some counter space, so most people grab their drink to go and head back toward gates or nearby seats.
Pricing runs higher than downtown Guam: figure around $4–$5 for a basic latte, about $3 for brewed coffee, and $3–$5 for pastries depending on what’s left in the case. The food range leans heavily on pre-packaged items and reheated pastries; nothing here replaces a real meal. If you want something more substantial, look elsewhere in the Main Terminal for hot food before circling back for coffee.
With a public rating down near 1 star, set expectations low on both service speed and drink consistency. Baristas may move slowly when several flights board at once, and waits of 10–15 minutes for a simple drink aren’t unusual during peak times. Order basics like an Americano or brewed coffee instead of complicated espresso builds if you care about getting to your gate on time.
Practical tip: if your boarding pass shows a Main Terminal gate within 10–15 minutes’ walk, stop at Pacific Coffee before you head to the quieter ends of the concourse, because other coffee options thin out quickly.
