Peppermint is the type of place I like to go on special occasions. I've been here for my birthday two different years. Definitely somewhere you can get dressed up to go, have great Thai food, get good service, and see charming decor. The prices are good compared to other places, too.
There will definitely be a wait on the weekends and the tables can feel a little cramped together when it's busy, so be prepared.
Their Pad Thai is really good, but seems to come in a smaller portion compared to other Thai restaurants. Their curries are decently good and all of their appetizers are very good, especially the crab tempura, Shumai, devil wings, and the satays. The drinks are nice and strong as well!
Definitely one of the better Thai restaurants in the area! I recommend it.
