"Follow the outdoor neon sign that says "Only Kids Drink Milk" to this fine-dining speakeasy that ranks 10th on Asia's 50 Best Restaurants list. Head to the back of Mayrai Pad Thai and Wine Bar, go up the spiral stairs and past the open kitchen, and find a small dining area set for 12. One of Bangkok's most exclusive reservations, the restaurant serves a 12-course set menu of Thai chili–laden dishes that are an ode to Chef Ton Tassanakajohn's grandmother, Nusara. Highlights include peanut relish with seasonal vegetables and shrimp paste water perfected over the course of 80 years." - Diana Hubbell, Katie Lockhart
