The Best Pad Thai

there's a duo here streetselling the best pad thai i've tasted... price is just 30bht... though they only cook in the evening after the office they're parked in front of have closed... can't understand the signage... all i can remember is that it's on a white background with blue fonts and the prices are in red... they have basically an open cart where a large pan that looks like a bass drum... i hope you find them... i never let a night pass without munching them during my stay there with my wife...
