My friend who lives in vegas warned me that the prices were steep and the portions are small. And he was right. Everything that was on the menu was at least 2 to 7 dollars too expensive. I ordered the thai fried rice with pork and the nam prik ong (best thing I ever ate-food network). The thai fried rice was not only small, but also generic. The saving grace was the nam prik ong. Other than that, most of the menu items can be found at sanamluang in Hollywood, California (thai town). Sanamluang not only tastes better than Lotus of Siam, but also costs less and offers more portions. To be frank, I was tempted in giving this place a 2 star review. The nam prik ong was delicious, but wasn't worth the ten bucks I paid for it. The small serving of nam prik ong showed me that this place was nothing but a scam on people who can't get good thai food in Las Vegas. Alas, the nam prik ong did taste good, so I must give this place one star above two. Overall, I regret spending $20 something dollars here.
