The world consists out of two types of people: those who do believe it is worth paying decent money for a good steak and those who don't. STK manages to cater to both.
I certainly belong to the first category, I love a good steak and I try to include a high-end steakhouse whenever I visit Vegas. After a friend's recommendation and as we were staying in the Cosmopolitan anyways, we booked STK for 9 of us during our latest Vegas trip. My 14 oz dry-aged Delmonico was perfect, the taste was sublime and it was seared just like I requested. Although the waitress recommended one side per person, we went for 5 sides for 9 people. All of them were very good, especially the truffle risotto and the asparagus were big hits.
Some of my friends are not as big of a meat lover as I am and ordered a non-steak entree. I would call you crazy if you ordered something else in a steakhouse but all the dishes looked really good, even the fish dish (Dover Sole) looked great and my friends seemed to enjoy it. So kudos for STK to also please people who are less fond of steak.
All of us, both steak lovers and non-steak lovers agreed that it was one of the better or even the best steakhouse experience in Vegas!
