One Seoul toast truck had its griddle going by 6 a.m. and was done for the day by 11. It was a white snack truck among the office buildings of Mugyo-dong, in Seoul’s Jung-gu, about five square meters inside, and when Hankook Ilbo profiled the seller in July 2004, he was selling more than 300 toasts a day at 1,000 won each.
I think that closing time explains gilgeori toseuteu (길거리 토스트, “street toast”) better than a recipe does. It’s a cheap breakfast for people on their way to work or school. Everything on it, including the part that sounds wrong, makes more sense once you picture it eaten on the move.
What 2,000 won gets you
It’s a hot sandwich more than toast. Thin-shredded cabbage goes into egg and cooks flat on the griddle into a patty, the bread crisps next to it, and then the sauces go on: sugar, ketchup, and mayonnaise or mustard, depending on the stall. Ham and cheese are the usual extras.
The price has moved, though not by much. A May 2023 roundup of nine Seoul toast spots by the travel outlet Yeohaeng Toktok listed a basic toast at 2,000 won at six of them. One, right outside exit 1 of Hoegi Station and open from 5 a.m., used to be known for 1,000-won toast until rising prices pushed it up.
At the Cheongnyangni Station exit 2 stall, the roundup says, they ask whether you want it wrapped. Say you’ll eat it now and it comes in a paper cup. The editor’s advice was to take the cup, because this kind of toast is properly eaten walking.
The sugar is the part worth keeping
If the sugar is what worries you, that’s fair. Sugar on egg and cabbage sounds like a mistake nobody fixed. I’d still keep it the first time. It’s the difference between this and a plain egg sandwich, and it’s what gives street toast its danjjan (단짠, “sweet-salty”) taste, the slang word for food that’s sweet and salty at once.
The strongest case for the sugar comes from the franchise side. Isaac Toast started as a single small shop in 1995, began franchising in 2003, and now lists about 900 stores.
Its own brand page, which calls it Korea’s number one toast brand, says the thing that sets its toast apart from ordinary toast is a sweet sauce it developed itself. It sells that sauce as a product too. Nobody I’ve read says who first put sugar on the egg, though. Not the 2004 profile, and not Isaac’s page.
Some places will adjust it for you. The grandma toast shop near the Changdong alley market lets you choose how much sugar goes on, and the Yeohaeng Toktok writer recommends asking for more.
