What are you waiting for? Go, go on, There's nothing holding you back. Pick up the phone make reservations, gas up the ride, and drive to Lotus of Siam. Now!
I have been twice so I have barely scratched the surface. Literally everything I have tasted has been 5 star. The Nam Prik Ong was the dish on Best Thing I Ever Ate that lead me here other than that I have no recommendations. Well I do have an admonition, don't get the Pad Thai. You can get that shit at home son. It is great but why waste a trip to the best Thai food you have ever had by ordering the most mundane item on them menu? You don't go to Ruth's Chris for a burger do you? No you want a porterhouse with fennel butter. Don't go to Lotus of Siam for the Pad Thai come on man.
Man... I am getting hungry just thinking about this.
