I've been here twice, once for the grand opening and once more recently.
The first time everything went pretty well and the restaurant would have received a 4 to 5 star rating.
The last time I was there was with a party of 8. We waited 45 minutes for a table after being told the wait would be 15. The only reason we got the table so quickly was because we asked if something had come available - our buzzers hadn't gone off and no one had come to let us know something was available.
We were put in a corner where we were quickly forgotten. It took over an hour to get edamame and two medium sushi boats. Once it came out we quickly ordered 3 rolls hoping they would be ready by the time the boats had finished. An hour later they arrived. An hour for three rolls. In all we spent 3 hours at Stingray and probably 30 minutes eating. The other 2.5 hours were spent waiting.
The restaurant is nice and the sushi is good but the service was so poor that I would not go back.
Oh, and when the waitress finally showed up with the check she told us, out loud, that since we were a part of more than 6 (I think) that an 18% gratuity was included automatically. That was a bit audacious. Maybe she was just clarifying the bill but after her terrible service she is lucky that stop-loss policy is in place or her tip would have been tiny.
