Hungry and short on time? Panda Express might fit your bill.
We were staying at Red Rock, and decided to take advantage of their food court. From our hotel room, it was a bit of a haul to get to, but otherwise was pretty convenient, with the usual gamut of chain restaurants - like a Panda Express.
Got two combination plates (and some wontons) to go: a plate of fried rice with orange chicken and Beijing beef (not that good), and a plate of with chow mein (those noodles are wayyyy better than I remember) with mushroom chicken and broccoli beef.
We feasted on the Americanized Chinese grub in our room - there were no leftovers. Sometimes all you need is slightly-pricey, greasy food to keep you fed, and Panda served.
