Granted, I'm about to make this statement based on my first time being at an Oregano's in quite awhile (a few years maybe?), but once you've been to one location you've pretty much been to them all...and that's a good thing!
Oregano's has solid food & friendly service. This is probably like the fourth or fifth location I've been to over the years (the other ones were in Scottsdale & Phoenix). Honestly, the one thing about Oregano's I remember not liking as much in the past was their pizza (they have really good pasta & salads), but pizza was what I ordered this time and it was really good! It was a veggie pizza with sun-dried tomatoes, feta, and I can't remember what else but it was really good. Everything tasted fresh. We opted for thin crust, which I had never had from Oregano's before (maybe that's why I liked it better?).
I like Oregano's. I like this location. I like the fact that the Phoenix area has a local chain like this that's successful.
