When we went to STK in 2016 it had only been open for a couple of weeks. We had an early seating, around 5pm I think. The food and service were excellent, then around 6pm the DJ started. It was pretty low key at first, but as we were finishing our meal and getting ready to pay the music was getting louder. We were out of there by 7 so I don't know how much louder it got, but I'm glad we got out when we did. It was just DW and me, we were sitting close together, but trying to carry on a conversation with a larger group would just not have worked.
It's a weird concept--high end dining and nightclub style atmosphere. I guess it's working or they'd have been out of biz by now.
