With so many options for steak houses in Vegas it really comes down to price. At Gallaghers you will get a good steak and some New York vibes.
I had their "Dry Aged New York steak"(only the New York is dry aged) with no sauce. The flavor that dry aging gives the meat is very different but at the same time suddel. I had their sateed mushrooms as my side. The portions were very reasonable for the price.
Service was excellent, our server answered all of our questions and gave us plently of attention. I swear the water guy talked like a Jersey native haha.
If you're thinking of coming here be sure to make a reservation or you most likely will wait for a table.
