I've eaten at this local gem a million times & it is great each visit. The restaurant is pretty & service is always great. The location is a little sketchy in a strip mall but the food speaks for itself. Must visit if you love good thai food.
The soups are all good as well. The service has always been good, and attentive. Overall, Lotus Of Siam is among the better restaurants in Vegas, for quality of taste.. And, it's probably the best thai in the city as well. But, I must be honest. I've had better Thai in other places. So, to call this the best thai in the country is a bit of a stretch IMHO. But, many would argue, so I suggest to stop in and try it for yourself.
