Our experience with Sirio was short and a complete bust. We came in for restaurant week. Two diners in our party were set on the veal scaloppine. About a minute later, the waiter came by and noted they were out of veal. It was disasterous really, our friend has aversion to onions and it was the only dish without them. He looked over the regular menu for something suitable, and we dug into the bread basket. We found stale bread and rock hard butter. We were not off to a good start.
Restaurant week menu offers 5 entrees, you should have enough on hand to feed your guests. I could be more understanding if it were just before closing, but this was 7:30. Stale bread is never acceptable and rock hard butter is a major annoyance. I suppose in this case spreading wasn't an issue.
It was a major disappointment. Rather than staying and seeing this meal go from bad to worse we left. It was for the best, we ended up having a fantastic meal at Jean Georges next door.
