Meh- maybe it was the day, but none of the 3 baristas were overly friendly. I wasn’t even greeted as I stood at the counter, until after stood there for about 90 seconds or so until after they were done conversing with other patrons. The breakfast burrito was flavorful, but soggy. The coffee is tasty, but drip options were out when I tried to get a refill. decent experience, but nothing stood out enough to want to come back- especially since the coffee and burritos aren’t made on house, even though they are good brands Good if in a pinch, especially before going up the flatirons

The environment is incredible, nice and open with outside seating as well. The danish and croissant were tasty, but no offer to heat them up, which was a bit odd. Still, an amazing place!

smooth velvety coffee, with pretty good sandwiches ! I wanted empanada but those do take longer (15min) panini was however solid! It’s spacious are with lots of people studying or hanging out. Cool little shop inside too for mountain climber enthusiasts

Love the vibe. They don't have as many options as some other coffee shops but they have the basics and nice employees. It's the chill lounge vibe I look for in coffee shops.
