Food courts
Ploenchit Center Food Court
The top floor of the Ploenchit Center is one of the cheaper food courts along Sukhumvit Road, but with a good selection of Thai dishes. It is mostly popular among the local office workers, many secretaries in outfit have lunch here. It works with a coupon system.
Robinson Food Court
While still a decent food court, it is a bit more expensive than the others, and you might need to order twice get full. It is in the heart of Sukhumvit though, so a good way to get a cheap menu without having to dine at expensive restaurants.
While not as much an institution as in Siam Square, the food courts in any mall or department store are a good option if you're trying to survive Sukhumvit on budget and want air-conditioning. Just like in Siam Square, food courts come in many varieties, from basic snack places to more upscale dining. Most food courts use some variation of a coupon system; unused coupons are always refunded.
Emporium Food Court
A very upscale happening and crowd, this place challenges the idea of food courts as being simple places to have a snack after shopping. Park Food Hall serves an extensive three-course meal with wine in a dimly-lit atmosphere.You can also go to the regular food court, which is comparatively small and hidden behind the other restaurants, but cheap and often packed. At peak hours it's difficult to get a seat if you're alone. The prices have been increasing over the past year.
