Lotus of Siam has an impressive amount of great reviews on Yelp so we had to try it out on our last visit to Vegas. Love the food but the prices are pretty ridiculous & so is the wait. This place is located in a sketchy shopping center. From the outside, it doesn't look like much but the interior is really nice. The wine cellar is pretty impressive.
~ papaya salad - after trying Laos style papaya salad, Thai style papaya salad everywhere tastes bland to me & the one here is no exception :(
~ crispy duck curry - pricey but it is pretty good
~ pad Thai - decent but small portion
