The medical physicist at the site I worked came from L.A., so when I wanted to find a sushi place, I went up to him and he introduced me stingray.
I have been to other Sushi lounges in this area, and most of the places provides fish that had been sitting in the fridge forever (at least they smell like it) The quality of food in Stingray was not bad, as they were fresh enough. Chef's skill was alright.
Atmosphere was fine. Depending on what time and what occasion you went to that place (for dinner or for drinks), I think it is a good place to hang out.
You may need to wait for a bit in line before getting seated, but hey, I do not know how good a place can be if they are always empty seated.
I lived in Japan and California before, and I think Stingray deserves a good review in PHX area.
