As much as I wanted to like the ESPN Zone, I just can't get over the awful food. I've been twice, first time was OK - the second time, it was nasty. We got a Nacho appetizer and the chips were hella stale. I got a simple cheeseburger for dinner and it was gross. As hard as it is to mess up a burg, they managed to. It was like a microwaved patty. No grill marks, no fried burns, no flavor.
Probably an awesome place to grab a brew and watch the games - but stay out of the restaurant. 1 star food, 4 star hangout - I'll be generous and give them a 3-star. But in Vegas, why go 3-star???
