Great place for bingsu, but it can get very busy at peak hours. It's mostly self-serve, super casual, and great for desserts after dinner. Parking is free and surprisingly not as limited as the other food places in the area!
My favourite is the Injeolmi. It's a sweet and decadent mix of soybean powder, condensed milk, almond shavings, and mochi.
Overall, the bingsu is a good price to portion ratio. I recommend sharing one large between (at most) 3 people.
