Toko Burgers @ Al Makan is a burger stall trading from the Western Stall at 201D Tampines St. 21, #01-1155, in Tampines, holding a 3.4 Google rating.
A burger from a hawker stall is a different proposition from a fast-food one: patties are typically cooked to order, so expect a short wait and judge the basics first — a bun toasted so it holds its shape, a patty with a bit of char, sauce that seasons rather than drowns. Egg-wrapped, Ramly-style patties are a local staple well worth trying, and many stalls do their best trade after dark, so an evening queue is usually a good sign rather than a bad one.
For a fresh-grilled burger without the mall trek, Tampines has one right here on St. 21.
