Gangnam · Places
Hayes Mill Bakery
헤이즈밀베이커리 본점A sourdough bakery cafe on Apgujeong-ro 14-gil, in the back streets of Garosu-gil, open 09:00–19:30 every day. That is not early, but it is two hours or more ahead of Garosu-gil brunch places such as Noras (11:00) and Pinch Brunch Bar (11:30). It is known for open toasts: almond butter open toast ₩8,000 and avocado open sandwich ₩9,800, per Kakao Map. Kakao Map and two September 2026 blogs all give the same hours.
Isaac Toast Gangnam
이삭토스트 강남점A branch of the Isaac Toast sandwich chain in a side street (Seocho-daero 74-gil) on the Seocho side of Gangnam Station. It opens at 08:00 Monday to Saturday and is closed on Sundays, with a 14:00–17:00 break on weekdays. You order at the kiosk by the entrance; the Bacon Best toast was ₩4,500 per a July 2026 blog. A good breakfast to take away. Kakao Map and the July 2026 blog agree on the days and hours.
Jeonju Hyundaeok Gangnam Kyobo
전주현대옥 강남교보점A kongnamul gukbap (bean-sprout soup with rice) chain branch on Sapyeong-daero by Exit 9 of Sinnonhyeon Station — one stop from Gangnam on the Shinbundang Line, or a walk up Gangnam-daero. Kakao Map and two blogs from June and July 2026 give its opening time as 07:30, so it works for breakfast. The Jeonju Nambu Market-style soup was ₩10,000 per the blogs (₩9,000 on Kakao Map's menu), and you can add squid.
