Great place anytime. We went there at 11:30 am on a Sunday. There were 24 of us. Everyone could have what they wanted--breakfast or lunch. Plenty of seating. We could have drinks. Perfect.

Avo's has served Fort Collins since 1971. Our restaurant is open for breakfast, lunch and dinner, and caters to vegetarians and meat-eaters alike. We make our famous organic tempeh in-house! We are also one of Northern Colorado's premiere music venues. With two beautiful stages (one outdoors on our beautiful patio), we attract national and local acts alike. We host a killer open mic on Tuesday nights, and an excellent Bluegrass jam on Wednesdays. Our bar opens at 11AM on weekdays, 9AM on weekends--come in and enjoy our signature Bloody Mary, which is topped with a splash of Guinness! Kids LOVE our sweeping back patio, complete with treehouse, gazebo, water features and plenty of shaded seating.
