So this is known as the Fuzhou bagel (I'm not kidding, as was told by my good friend Wiki).
I can certainly see why it is named that way, for the sesame seeds and the rather tough bread texture did remind me of a good ol' sesame bagel. However, that's where the resemblance ends- this was filled with meat and/or mushrooms depending what you order so to me, it felt more like a baked Chinese bun instead.
My favourite was definitely the Chicken filling (ayam)– it had a good bread-meat ratio, and although the meat was a little dry, it was nicely flavoured with Indonesian chilli padi. A great protein alternative to the Western bagel if it's really called that, it certainly makes for a good snack/breakfast. 👌
