Wolfgang Puck Express is one of the few dining options in the D gates at McCarran that sounds remotely appetizing. But, if you decide to dine there or get food to go be prepared to wait. My pizza took about 15 minutes and when it gets really busy don't be surprised if your wait is longer. It's also common to see confrontations between staff and customers. During my last visit I saw two different customers lose their cool because they didn't get their pizza sooner. So, if you're in a hurry dine elsewhere.
The food itself was disappointing. The crust on my pepperoni and mushroom pizza was limp and the toppings slid right off after picking up the first slice. Maybe I should have waited for it to cool down and for the cheese to congeal before eating. What was worse was seeing the huge pool of grease in the center of the pizza. I needed about five napkins to soak it all up.
I've had decent food from this particular WP Express before, so I won't rule out a return visit. But, this last experience was a fail.
