I got to hand it to the staff, they are really patient and have to put up with a lot (keep in mind this is right next to ASU). I have so many stories I could tell of our late night adventures to Denny's. I usually ended up being designated driver, and had to be the one to apologize to the staff on behalf of my roommates.
I give it four stars because when we would go during the day (when they were sober), the staff seemed even more moody then the staff that runs night shifts.
