Tips for Visiting Restaurants & Food
Learn the Spice Scale
Say 'mai pet' for no spice, 'pet nit noi' for a little spice, or 'pet mak' if you want it Thai-hot. Most cooks will default to a toned-down version for foreigners unless you specify otherwise.
Follow the Crowds
The busiest street stalls are almost always the best — high turnover means fresh ingredients and a recipe that locals vouch for. An empty restaurant at dinner time is a red flag.
Ice Is Safe
Factory-made tube or cylinder ice (used in virtually all restaurants and stalls) is made from purified water and is safe to consume. You don't need to skip the iced Thai tea.
