I make it a point to try all the fancy burger places that pop up in Vegas.
Holsteins is definitely one of the best. I'd say the burgers are probably better then Burger Bar @ Mandalay Bay. And i'd probably end up frequenting Holsteins more then Burger Bar due to the Cosmo being in a much better location on The Strip.
I got the Gold Standard which is the sirloin burger with all the trimings. I knew the burger wasn't going to disappoint after the first bite of the nicely toasted bun. You cannot believe how many burger places fail to toast the buns correctly.
The aged goat cheddar was a little too much though I think. Halfway into the burger and the taste of the cheese was getting old. It might have been better with just regular aged cheddar. I did find that adding some horseradish to the burger was a nice compliment to the goat cheese.
You'd think a good burger would be easy to make but a lot of places fail. You want to be able to taste the burger patty, the cheese, the bacon, and whatever else is on the burger both distinctly and as a combination. A lot of places make their burgers so you can only taste one or two of the ingredients. Holsteins does a good job of creating a "complete" burger experience :)
The other main attraction of Holsteins is the alcoholic shakes. They were ok i guess, none of the shakes really have much alcohol in them so to me these are basically just regular shakes.
