HeyYumi helps you find where to eat, drink, or go out in Korea — restaurants, cafes, bakeries, dessert shops, and bars — and book a table without leaving the chat. Every venue comes from Yumi's own refined, cross-verified dataset (346,000+ venues, strongest in Seoul, Gyeonggi, Busan and Jeju), each shipping with a confidence score and a last-checked date so answers stay grounded rather than guessed. Narrow results by 40+ food & drink attributes — neighborhood/station/landmark, cuisine, price, atmosphere, parking, pet-friendly, private room, vegan options, English-speaking staff, open-now, and more. At Yumi partner venues you can send a real reservation request to the owner right inside ChatGPT and get a confirmed/declined answer back.
