This morning I woke up, filled a big travel mug with fresh coffee, and poured a little syrup and butter into a snap lid container. Then went straight to this booth at the Yulin Market, whose sign proclaims "Fresh and Tender Corn Cakes":
The booth has only been open this summer, and often has lineups. They grind the fresh corn on the spot. I served the corn cakes at a brunch once, and people couldn't get enough. Here is my Y2 worth, before they got dunked in the butter and syrup:
There is a small square outside the market with benches, though it is busy in the mornings.
UPDATE OCT 09 - This stall no longer selling corn cakes. Fresh potato chips instead. Still worth a visit.
Address: Yulin market, between Yulin Road and Yulin Street. 玉林菜 市场 玉林西街 12 号
