Upstairs in this shopping mall is a great food court. Effectively you can sample the best of what of what you could find on street stalls without any hygiene concerns.
You get a plastic card when you enter the court. If you get food from a particular kiosk they simply swipe your card in a machine. When you leave the court you hand over the card and the cashier calculates your bill. We got to try some great Thai food for at most £2 each.
