Yuma late night
Yuma is not a good late night town. I know of no independent restaurant open until 10. There is an IHOP open 24 hrs at the 16th St exit. We also have a Filiberto's on 4th Ave a couple of blocks south of 16th. The drive thru is open 24 hrs and the asada and pollo asado burritos are good there.
Another possibility would be to cruise west on 8th St. Probably some of the taco stands would be open after 10, but I can't say for sure because I don't go out looking for dinner that late. Wish I had more info, but this is the best I can do.
