Gate-side caffeine fix in DSM’s Terminal 1
Right past security in Terminal 1, Mill Supply Co. runs from 5:00 a.m. to close, catching the first Des Moines departures and most of the late ones. It sits in the main concourse after screening, so you don’t need to backtrack far from the gates to grab coffee or a snack on the way to boarding.
This is a quick-service café with a clear <$10 focus, so you’re looking at drip coffee, basic espresso drinks, and grab-and-go food that won’t crush the per diem. Think breakfast sandwiches, pastries, and simple lunch items rather than a sit-down meal. The line moves fast because there’s no table service and payment is straight at the counter.
With DSM being a single-terminal field (Terminal 1 only), Mill Supply Co. works as the default caffeine stop once you’re past security, especially for those 6:00–7:00 a.m. flights. It’s practical for topping up a water bottle with a purchased drink on the side, then walking straight to boarding without looping the concourse twice.
Food quality here tracks with the price tier: it’s “airport basic,” not destination dining, but it fills the gap between the 5:00 a.m. opening bell and when other spots fully spin up. If you want something warm before an early American or Delta departure, a hot breakfast item and coffee here usually land quicker than waiting on a full restaurant kitchen.
Tip: If you have a tight connection under 40 minutes at DSM, hit Mill Supply Co. first as you exit security in Terminal 1, then walk to your gate with everything in hand instead of gambling on another option being closer.
