Looking for a castella bakery in Bucheon that isn't too sweet?

Jinsim Castella Bucheon (진심카스테라 부천점) is a takeout-only bakery I visited while searching for a place in Bucheon that makes castella (Japanese-style sponge cake) properly. When I want a proper dessert in Bucheon, I skip the obvious ones and often reach for something that goes well with coffee and isn't heavy, like castella. It works as a snack, and with good ingredients it can even stand in for a meal, so I find myself eating it often, but among ordinary Bucheon bakeries, hardly any make castella really well. So I looked around, and the place I ended up at was Jinsim Castella Bucheon, a bakery tucked away in Sangdong, Bucheon.

Can you add fresh cream to the choco castella?

Even with the plain choco castella, you can order fresh cream separately, and the cream can be regular fresh cream, choco cream or mocha cream. They don't hold back and put in plenty.

For the fresh cream castella, they spread the cream between the fluffy layers of sponge and pack it right away. The white cream against the yellow sponge looked so appetizing. The choco castella has a brown sponge with chocolate chips here and there, and the sponge looked moist and soft even without cream. Still, I wanted something a bit sweeter, so I added fresh cream.

To try the choco in a different way, I added cream separately instead of getting it filled in, and had the cream packed on its own.
