We've eaten here a few years ago but it looks like that Yelp page has been closed so I guess a new review is in order.
While they don't take reservations, if you get there early enough, the line is maybe a 10-15 minute wait. This is absolutely one of our favorite restaurants in Vegas. I don't think you can go wrong with any burger at this place but I've got to recognize the Ultimate Cheeseburger, which is my go to item. The buns are quality, the burger is juicy and flavorful, and it has three kinds of cheeses mixed together in what can only be described as my version of heaven. My husband had the Lobster/Shrimp burger which has a shrimp/lobster type patty and pickled veggies on it. It's really a different option then the traditional burgers.
Lastly, you need to get one of their milkshakes. We didn't last time we were there so we made a point to try the Oreo Creme Brulee Shake on this trip. It is so rich and the flavor is better then just your average oreo shake because of the creme brulee pudding on the top. The cocktails we had were also on point. I don't remember what they were called but the white sangria I ordered was our favorite because it had this really nice cinnamon after taste. Do not miss this restaurant!
