London Bagel Museum Jamsil is a bagel shop on the first floor of Lotte World Mall in Jamsil that sells bagels and sandwiches. Its menu includes a cheese bagel, scallion cream cheese, and pretzel items, and both dine-in and takeout are available. For dine-in, you put your name on the waitlist at an on-site tablet or through CatchTable, while for takeout you enter and order after being contacted. The drawback of dining in is the long wait inside the crowded space.
