These guys change their menu way too often which is why I find myself eating there less and less. I have lived in Summerlin for four years, and my first two years here I ate at LBS at least three times a month. Now, it is about once a quarter. The reason is there menu seemed to change often, and when the got rid of the make your own burger I could not make what I liked if they had removed it from the menu.
Their food is delicious and I have no problem paying $10-$15 for a great burger. The mound of fries is really too big, but I still eat them all when I get them because they are some of the best fries ever. The side salad with their balsamic dressing is tasty; I usually opt for that since the burgers hit the waste line pretty hard.
My favorite burger is the braketology burger when it is on the menu.
The beer selection is great too. And if you just feel like total fat Armageddon, get a milkshake as well.
