Eat like a local
Because you order pad Thai every time you eat takeout, you're obviously going to have to start with it here, too. But after that, expand your taste buds (and spice threshold) with a bowl of tom yam (a hot and sour soup made up of lemongrass, fish sauce, and crushed chili peppers) or soma tam (a green papaya salad with a kick). Curry, coconut, fried noodles, and spicy plates are all representative of authentic Thai cuisine -- be sure to have slices of watermelon or a sugary drink on hand in case things get too hot. Thailand also boasts a rich range of fruits you don't eat that often at home, including jackfruit, mango, durian, papaya, rose apples, and the pod-like tamarind.
