I've gone to Green on several occasions. Food is always fantastic. I get the Buffalo "wings" and the "Big Wac" usually. Prices are a tad high, but not really for being in Scottsdale, and for the unique kind of food they offer.
I will give two criticisms. First, I often go with my non-vegetarian wife, and I will have to say their choice of foods for her is very limited. I'm not saying they should offer non-vegan foods, but I'm saying they could add a few more "normal" non-meat choices. Maybe a few more salads, a veggie pizza, etc. She had the Mac & Cheese which is something that might attract someone like my wife, and even I will have to say, it wasn't very good.
Second, the cleanliness of the place, and the overall feeling of the place could be improved. While there seems to be all types inside, and it has a distinctive hippy vibe. If you don't have a nose ring and dreadlocks it gets easy to feel out-of-place, which is a shame because the food is very good. Still, I do feel they should invest a bit more time in atmosphere improvements. I know my food doesn't contain cows or pigs, but I'd like a bit more confidence that it doesn't include bug parts.
