Before I continue, I'd like to make it clear that this is a review of STK in the Cosmopolitan Hotel, not the Cosmopolitan Hotel itself which was an amazing place to spend Valentine's Weekend.
Read the other reviews here that complain about the overbooking issue. We had a reservation for 10pm. We checked in TWICE. Both times we were told that our table would be ready shortly. After waiting over an hour, we decided to bail. My husband told the host we were leaving, and the host told my husband that we had never checked in, but if we wanted to wait an additional 15 minutes, he would get us seated. Yeah, right. We said "no thanks" and went elsewhere.
That night, I found a cancellation notice in my email account from Open Table. It was sent at the exact moment that we left the restaurant. Oh I'm sorry STK, I did not cancel my reservation. You cancelled it for me.
