Lotus was one of the most highly recommended places for me to try when I first moved here. Driving eastbound down Sahara into a semi run down shopping center lowers your expectations immediately and makes you think "Ok this place sorta looks like a dive, but I'm sure the food is awesome". Once you walk through however, it is surprising how classy and well put together this restaurant is!
I've been lucky and haven't had to wait more than 15 minutes for a table here, but i would suggest calling ahead to be safe. The staff here is very professional and friendly and the feel is very authentic.
I always order the Pad Thai because I am very interested in how each place puts their spin on it. Lotus of Siam has a very good Pad Thai but not the best I have ever had, so i can't warrant giving it a 5 star rating.
I will say that the menu is very expansive and the price point is great considering how well put together everything is inside and all the buzz going around town about it.
I find it as a safe place to take my friends since many have heard about the legend and the menu is flexible and has something for everyone.
