I ducked in here to escape a sudden downpour. It's a renovated factory, so it really feels like an abandoned building, and the restroom was a bit scary (lol). I was full so I only had a drink, but next time I'd like to try some of the bread that looked delicious.

This shop is super popular. The iconic brown paper bag is so aesthetic. The bread itself is good and tender

I went for breakfast. There were so many delicious-looking breads, and each one was huge. They were topped with strawberries and Shine Muscat grapes, making me want to buy a lot, but one or two are plenty. There isn't a ton of seating, but it felt like the turnover was pretty quick.
