Loooove this place but be warned that their dishes are SPICY! They do let you choose the spice level, so don't let that turn you away from this delicious place. Definitely comparable to Ha Long Bay, the other popular Thai/Laotian restaurant in Madison.
The location is pretty convenient on Willy street, and the service was pretty fast. The restaurant is TINY though, so I would expect a wait unless you make a reservation (they let you if you're a party of 6+!)
In general, this place really surpassed my expectations, but I was definitely surprised by the spiciness. I got the level 2 (Careful) spice level and it was quite fiery.
