Gate-area caffeine in Terminal 1
Right past security in Terminal 1, Mill Supply Co. Coffee & Bar covers the basics: espresso drinks, drip coffee, and an all-day bar setup. It sits on the main concourse used by Allegiant, American, Delta, Southwest, and United, so you walk by it on the way to most gates at DSM. It functions as the default stop if you want something stronger than the coffee at your hotel before a 6:00 a.m. departure.
Hours track the flight bank, typically opening by around 4:30–5:00 a.m. for the first wave and staying open into the evening when the last departures go out after 8:00 p.m. That means you can usually get a latte before an early American 5:45 a.m. flight or a beer before a 7:30 p.m. Southwest departure. If you land on one of the last arrivals closer to 10:00 p.m., expect it to be closed.
Prices line up with airport norms: count on around $4–$6 for espresso drinks, $3–$4 for brewed coffee, and $7–$10 for wine, beer, or basic mixed drinks. Food options lean snacky rather than full meals, so think packaged pastries or grab-and-go items in the $4–$8 range. If you want a proper sit-down plate at DSM, you’ll likely walk a few gates further to one of the main restaurants instead.
Seating is limited to a small bar area and nearby public tables on the concourse, and it fills quickly before banked departures around 6:00–7:00 a.m. and 4:00–6:00 p.m. Expect to take your coffee back to your gate if your flight boards in under 30 minutes. Power outlets are hit-or-miss here; you’ll usually find more reliable charging at your exact gate.
One practical move: mobile check your gate first, then stop at Mill Supply Co. on the way, because everything sits in a straight line in Terminal 1 at DSM and you won’t backtrack more than 2–3 minutes.
