For those who don't like eating on the street, it's also possible to enjoy "sit-down" fast food, Bangkok-style. Here's one of the popular local spots to drop into for a bite to eat. Notice the well-used chopping block for cutting up all those fresh meats and vegetables.
Of course, if you prefer BBQ duck, that's available too. Don't the heads in the left-hand tray look delicious?
But don't expect too much in the way of cleanliness. Here's a picture my intrepid photographer managed to catch of the kitchen attached to one of the better-looking fast-food shops.
