Avogadro's Number

605 South Mason Street

Avogadro's Number has been a cultural staple of Fort Collins for over 40 years. Known to our loyal patrons simply as "Avo's", this historic music venue and restaurant has captured and held the hearts of generations of Coloradoans. 

Avo's is a unique double-venue, with both an intimate indoor venue, and an expansive outdoor venue. The oudoor venue is open May through October, and boasts water features, a treehouse, a large gazebo, and concessions so that patrons can enjoy beer and barbecue without missing a note. 

Our restaurant features a large sandwich menu, delicious appetizers, salads, homemade deserts, and a full espresso bar. We produce our own organic tempeh, and have become known for our delicious tempeh burgers and subs. Artisan tofu is also produced on-site, by a worker's cooperative, known as Mama's Tofu Collective. 

Avo's Bar occupies the southern-most third of the property, and serves the best Bloody Mary in Fort Collins. Local artists display their work in the bar, where there is plenty of seating, and lots of natural light.
