This is a very solid Thai restaurant. It has hints of Chinese fusion with dishes such as wonton soup, orange chicken, and complimentary wonton appetizer, but overall it's a solid Thai restaurant to add to the Vegas list of great Thai cuisine.
The beer and wine menu is pretty limited compared to other Thai restaurants, but the food is great. The look and preparation of the food might be one of the best in Vegas. The pad Thai was a gourmet dish that looked absolutely spectacular. And as far as spicy goes this might be the best bang for your buck at good Thai in Vegas. Desserts are supposed to be their specialty but I didn't try any this time around.
Arawan is worth a try. Not too expensive and good portion sizes make it a great stop if in the area. Or come during lunch if you can for their cheap and great 3 part lunch deal which is tough to beat in Vegas
