Split the signature lineup into sweet, savory, soft, and shareable categories, and a first visit gets a lot easier to navigate than chasing every name from a list.
Walk into the Sungsimdang flagship for the first time and the sheer number of items, moving fast through a quick-turning line, makes it easy to grab everything you recognized from a blog post, and end up with a bag that doesn't match anyone's taste. Instead of buying equal amounts of every "signature" item, sorting by role: sweet bread, savory bread, a firm baguette, a soft roll, an easy-to-share baked good, makes it simpler to balance what you'll eat today against what you're bringing home.
Prices, branch availability, and stock shift often enough that this list works better as a role-based reference than a ranking. For exact ingredients and allergens, the official label at the counter on the day you buy is always the final word.
