Tips for Visiting Restaurants & Food
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.
Use Grab for Delivery
The Grab app works for food delivery across Thailand, letting you order from street stalls and restaurants alike. It's invaluable on rainy days or when you want to eat in your hotel.
