I like to put onions, mushrooms, and cheese on a plain burger..sort of like a Philly cheesesteak!! The fixin's turn a plain burger into a meal. My daughter (the vegetarian) takes the cheese sandwich and adds veggies from the bar. Not bad for the price!
Pecos Bills is probably the best of the "don't have to have priority seating" places in MK...... Glad they expanded it a few years ago.
I also like the chicken and fish at Columbia Harbour House.
