I've tried all the Thai restaurants in the Charlotte area, and I have to say this is the most authentic tasting. All of their basic Thai stir fry and noodle specials are spot on - even beating out the ever so popular Thai Taste (on East Blvd).
Favorites:
Appetizer: Mee Krob, which is classic chicken lettuce wrap. Other places give you noodles with a tiny little bit of chicken. But Monsoon's can be eaten as a whole hearty meal. Their version has a lot of savory gravy (so if you are into the dryer stir fried chicken wraps, this may not be for you)
Stir Fry: Pud Prig Pow, which is the classic thai basil stir fry. Nice flavor, with good amount of basil.
Noodle: Lard Nar. This one isn't always available at some of the other Thai places around town. So seeing it on the menu, I had to try - and I was delighted.
Aside from the good food, the staff is friendly and the service is fast. Price point is comparable to other Thai places around.
