Pad Thai Loong Pha makes only one thing—pad thai—and it’s been doing this to perfection for more than 40 years. Named after the owner, Uncle Prapha, the pad thai shop prepares its al dente chan noodles the traditional way, and cooks with charcoal instead of gas. Try the egg-wrapped pad thai sen chan mun goong (chan noodles with shrimp and shrimp fat).
