Avogadro's Number, "Avo's" to anyone who has lived in Fort Collins, is the long-running campus-adjacent restaurant on South Mason with weekend breakfast starting at 9. The site lists hours of 11 to 8 Monday through Thursday, 11 to 9 Friday, 9 to 9 Saturday and 9 to 8 Sunday, but it does not state a dog policy or describe its outdoor seating, so call before bringing yours. It is right on the Mason Trail and MAX line, two blocks from CSU.
