I typically do not give one star reviews. However Pan Asian deserves it. It was a very disappointing lunch stop at Mandalay Bay.
We were roaming around Mandalay Bay on Christmas and Ian suddenly uttered the dreadful words "I am hungry". Most of the restaurants at Mandalay Bay hadn't opened yet so we proceeded to their food court before he turned cranky. We got Ian a pizza and the Mrs settled on grabbing her lunch at this place.
After placing her order (Broccoli Beef with rice) and paying close to $11, she received the smallest portion of a lunch plate ever at any restaurant. The quantity of food is probably less than half a panda express lunch. You would have to order two portions at $22 to appease your hunger.
The food itself was doused in soy sauce with minimal quantities of beef and broccoli (see for yourself in the picture). Offerings in their menu are very limited as well.
I do not recommend to rely on this restaurant for your dining needs.
