This place reminds me of a college dorm. Christmas lights overhead when you first walk in, and Polaroid photos from the cafe's opening, along original paintings and drawings displayed on the wall. The workers I've encountered were college students as well. It seems like a place that a group of friends started and carries that vibe pretty well.
I would't recommend getting your drinks here. The baristas are a hit-or-miss-- I usually get too much syrup. The bingsu portions are large and the toppings are fun, but the fun ends when you ring up your order. Worth visiting if you've never had bingsu.
