Cafe Rio is better than costa vida
Crumbl is the best cookie place
Rockwells ice cream is my favorite in all of utah
I’d also add J-Dawgs which is a local joint. Started out in a shack right off of campus and has turned into like 6 stores all throughout utah. They are “just hot dogs” but they are amazing. Steve young, Andy Reid, Joe Flaco(friends/teammates) with former byu player and other random former BYU legends have all signed their tin foil from J dawgs and are featured on the wall.
