What customers say

Flatiron Coffee in Boulder offers a delightful coffee experience! I recently tried their latte and cappuccino, and both were incredibly tasty. The latte had a perfect balance of smooth espresso and frothy milk, with just the right amount of sweetness.

Staff are attentive and friendly. Coffee quality was average and slightly below my expectations. It is a small cafe but it feels spacious inside. The atmosphere is calm and the design is pleasant. Overall it is a suitable place for a short break.

★★★★★ — Ozitheexplorer, 2025-12

This is one of my new favorite places. The coffee is great, nice and strong. There’s a good amount of space to sit and enjoy your coffee with a nice book. The employees are very nice and pleasant, and the place is relaxing.

★★★★★ — Di, 2022-01

This little coffee shop is in a small strip shopping center, conveniently at the northwest corner of Arapahoe Avenue and 28th Street. We were foiled in our attempt to get coffee at The Dairy Center, but this spot was quite close.
