I had dinner with a girl friend here a few weeks ago. Carlos O'Brien is a chain restaurant we decided to go to since we were in the area. We visited the scottsdale location. The restaurant offers a wide range of mexican cuisine. They give a generous amount of food with each plate. Chips and 2 types of salsa is served as an apetizer. The food was good but not impressive. We were seated fairly quickly even if the restaurant was busy when we arrived. We noticed that not all waiters spoke English, however with our beginners Spanish skills, we were able to communicate just fine Overall a good time here. I would go back.
