If I was just reviewing the quality of the food, I would say four stars...but the overall experience I had at STK was essentially ruined by extraordinarily poor service.
Pacing was awful. We waited 15 minutes to get water. We waited another 10 minutes after order wine. The time from the time our salad plates were taken away to the arrival of our entrees was pushing 45 minutes.
This was a Wednesday night at 9:30 p.m. It was not busy. I would never eat at STK on a weekend.
The other thing that I have to mention is that this is a reasonably large restaurant with a single, private bathroom for men and a single, private bathroom for women. I don't know how that meets building codes--but if you go to STK and have to use the restroom, do yourself a favor and leave the restaurant. There are large public bathrooms just across the hall. You will save yourself time and frustration...and you'll be waiting forever for your food, so you might as well get in a little exercise.
