OK listen, I get it...you are in a swank hotel, you have a trendy ambiance but your food is just "OK" at best and your service a bit pretentious...get over yourself!
This is the second time I have dined at Lemongrass (previously lunch) and now dinner...both times, same exact experience. The staff has serious attitude over God knows what. Vegas is a tourist destination at the end of the day and service should be front and center every time, for every customer. Lemongrass is kidding itself if they think otherwise.
The food is just average...Thai food is usually good at most places...this is your typical fancy Thai spot that just misses the mark. The spring rolls are average, the cucumber salad...meh. The penang curry w/shrimp had a slight kick so was the best thing we ate since it actually had decent flavor. The pad thai was just plain boring.
Wine selection is average...nothing crazy but then again, at a Thai restaurant, can't come in expecting spectacular vino selection.
Please do yourself a favor and skip the nonsense...find a hole in the wall Thai resto off the strip and satisfy your belly and your experience. Again, the snooty service is the biggest turn off here.
