I have spent a lot of time in Laos and Thailand. My wife is Laotian. In our household we eat about 50% Lao and 50% western cuisine. When we heard about a new Lao Thai restaurant, we were enthusiastic to try it out.
The food is clean, fresh and very good. The presentation is better than most Lao restaurants I've seen in the US. The menu is as authentic as you can make it and still have western customers - meaning, there will be no tendons, intestines or feet. Learn a little about Lao cuisine by going to Lao Thai; it's the real thing.
Personally, I will return there again and again - anytime we don't feel like cooking but still want our Southeast Asian comfort food.
