Hole in the wall, but SUPER WELL KNOWN! I have lived in Vegas for over a year, and a friend from home told me about it. It is off Sahara hidden in a shopping center. It looks tiny, but once you get inside - it's huge!
Food - You can't go wrong with anything you order. The best things that I have tried are the Garlic Prawn, the Pad Thai, and the Short Rib Panang. The prawns are deep fried, but they are delicious! You will see the person at the table to next you have them and NEED them! I always order Pad Thai, and I found my new go-to place to get it from. The short rib Panang is sweet, and the short rib is juicy. It absorbs the flavor and melts in your mouth.
Ambiance - Always busy, but definitely worth the wait. You may want to call in at least a few days in advance to make a reservation to ensure you get a table, and don't have to wait.
