I like most of their dishes, but it's quite sweet overall compare to southern Thai dishes for me. I usually ask them to put less sugar & chilly in my Tom yam Kong , it goes well with pineapple rice.
The Alfresco ambiance and Thai folks there said it all, They are the best.
Order some beef green curry that goes well with steam rice, if you haven't taste some from them, I promise you they are superb. Sweet and sour Fried bass are great too. At the end don't forget their coconut milk desert to round up your meal, it's just divine. This deserts are bad for the weaker stomach that are not used to coconut milk though.
