I've been eating Oregano's for about ten years now and after switching to vegetarian it is still tops on my list. Their Veggie Wedge is really delicious and there are still many meatless options when dining at Oregano's.
The Pizza Cookie is always on the list of things to eat and we always get it half/half.
In ten years I have never been disappointed by the staff members or the food. Great people, great fun and always great food.
The new Dobson/Southern location is the closest to my home so I have been eating there since it opened. The location in Tempe and Old Town Scottsdale have been visited in the past.
Parking has consistently been an issue when going to Oregano's, but the Mesa location has plenty compared to the other two I have visited.
Enjoy!
