THE PATTY

Griddled to order.
Never from a warmer.

Every patty hits the griddle when you order — seared crust outside, juicy inside. That's what old-fashioned means, and it's why our regulars say the patty is the reason they return.

THE PLACE

A 1970s American diner,
rebuilt in Seoul

Vinyl on the table, Atari on the shelf, booths like the old days. Come hungry, stay for the vibe — it's half the reason people take pictures here.
