Of the food events in Vegas this one at this location is my favorite. Well organized. Casino right there for clean restrooms for those unwilling to use the porta johns (). Huge selection. We visited 6 different trucks. I suggest getting just one thing to split between 2 or 3 people from one truck at a time to be able to enjoy as many trucks as possible. Avoid full meals from one truck. Two stages. One with live music and food eating competitions. The other stage with a DJ and dance floor. A decent amount of space to sit.
Here's a tip. Park across the street at Galleria mall off of Mall Ring Cir in that small parking lot next to Panera Bread and Alfred Angelo and walk over. Much easier and it doesn't hurt to walk off all the grub.
