Kaldi's Coffee

This Kaldi's runs as a drive-thru. The Zumbehl Rd outpost in St Charles is a small St Louis-chain store with maybe a couple of indoor chairs and some outdoor seating, and the window does most of the volume. Drivers on their way to the airport use it as a fast pickup, which is the use case the location is built for. Regulars compare it favorably to the Chesterfield location for coffee quality, which is the kind of intra-chain ranking that tells you the customers care enough to compare. Service through the window is quick when it's working, and the line moves at a pace that respects people who have somewhere to be. A few customers have flagged rude staff and prices that creep higher than they expect for what the chain has trained them to pay. So go in calibrated and don't be surprised by the receipt. The vanilla iced coffee comes up most often in regulars' orders. A seasonal ube latte rotates through and is worth ordering when it's on the board for people who want something different. On the breakfast side, the bacon cheddar muffin has its small fan club that mentions it by name, plus breakfast sandwiches, power bowls, and breakfast burritos for people who want a meal with their cup rather than just caffeine and sugar. The indoor seating is essentially decorative. A pair of chairs is not a room. The outdoor seating is the better option if you have to wait, but the better answer is to plan for the window and keep moving. Best for drivers who want fast, quality coffee and breakfast without leaving the car, and for early commuters who treat this as the airport-route stop. Not a sit-down spot and not for laptop work, given how thin the indoor footprint is. The drive-thru is the product. Once you understand that, everything else about the location makes sense and the price-and-staff complaints land in their proper context.
