I absolutely LOVE this place! The atmosphere is fun, welcoming, and full of good energy. The food is delicious, the staff is always friendly, and the events are such a great touch. I saw someone complain about prices, but honestly—they’re totally fair and competitive for Boulder. Running a small business here isn’t easy, and this coffee shop does it beautifully. One of my favorite local spots, hands down!
The absolute best coffee house in Boulder now. It’s cool as a coffee joint, but made perfect by being cycling centric. Great vibe, amazing food, coffee is great, and the bikes retail section is fabulous. It’s like being transported to Girona Spain. All rides should start from here!
This place is amazing! I have been a regular at Cassiopeia for several months now and consistently had good experiences. Some of my favorites are their espresso drinks, the Giro sandwich, and Boulder Roubaix wrap. I also love the indoor bike parking! In the rare instances I had a minor issue with my order, the staff are quick to address it when brought to their attention. A true hidden gem in Boulder!
The best female-owned and operated business I have ever been to. They focus on community and a wonderful experience. Cassiopeia is a phenomenal place to grab food, coffee, or work remote. They only serve the highest quality ingredients. Added bonus if you're a cyclist: They offer indoor bike parking, show live bike race coverage on a projector, and have fantastic bike related offerings.
Fantastic social scene for the cycling community here in Boulder. There is great food and healthy choices along with the best coffee in town. They also host weekly rides for different ability levels along with women only rides. There are also weekly talks on topics like nutrition and training.
A warm and cozy cafe in general , but also for cyclists. Great atmosphere, clean, and great sandwiches and coffee drinks. They have bike hangers to park your bike, and a service shop right next to the cafe. Will be my go-to stop in Boulder mid-ride in the future!
Awesome atmosphere supporting women in cycling, but also a phenomenal cafe! The waffles are so delicious - great crispy exterior with perfect amount of sweetness in the sugar coating. And their chai was some of the best I've ever had, made from scratch! Service is so nice and kind.
Went here just about every weekday for three weeks as my dog was being treated for cancer at CASE. Great vibe and some of the best matcha I managed to find in Boulder. The music isn’t too loud and the acoustics are good enough you can easily take work calls without issue. The WiFi is solid as well, which especially helps as this is an AT&T dead zone. The breakfast food was decent, but the BLT was a total standout. I ordered it for breakfast a lot. The beet latte was surprisingly great as well. I also really liked the employees - they are so friendly and would even bring you the drinks/food if things weren’t too busy. Restrooms were very clean as well. While I wont miss driving to Boulder everyday I will miss Cassiopeia.
Stopped in this morning because we didnt want to drive to a Syarbucks. Best decision of the day!! This little gem is Awesome!! Our food was Amazing!You can't go wrong with anything on the menu, and the service was impeccable!
Such a wonderful place to relax. If you need a place to work, there are plenty of tables and plugs too! The espresso was great, the atmosphere was welcoming, and the staff are friendly. Also it’s worthwhile to stop by their shop. They have such cute clothing and accessories.
