When this existed it was... my favorite valley location of Oregano's.
***Now, I say just go to Flagstaff. Hee. It's a good excuse to get out of town.***
If it's a loooong wait, and you don't mind a little ambient noise go ahead and sit in the bar. You can usually sashay right in, grab a spot and be happily full in a fraction of the time it would take to get through the full restaurant experience.
However, if you have the time the patio is worth waiting for, and the little house full of tables is cozily warm and full of divine smells.
I recommend trying the big ol' ravioli with the Big Rig sauce (a variation on the menu version). It comes with a slice of garlic bread as big as your head and you'll probably be able to eat leftovers for breakfast!
***The big ol' ravioli has been REMOVED FROM THE OREGANO'S MENU - which means if you love stuffed cheesy pasta Oregano's is no longer the place for you(us)!***
