I came here after dinner since it was close by. It was pretty full with lots of young people. We ordered a large black sesame and small green tea bingsoo at the counter.
Quite a bit of time had gone by but I tried to tell myself to be patient. You could see the 3 staff behind the counter working and not slacking off. I had to go up to the counter to ask about our bingsoo when another customer who had come in after us had already received his. The girl who took my order couldn't even remember taking my order and the other girl had to print off my order again. They had forgotten my order! They apologized and said that they would make it right away. Some more time goes by when yet another customer gets to his bingsoo before we do! I'm baffled at this point. They forgot our order, told us we would be next and then made another customer's order. I'm pretty peeved at this point. I go up to the counter again and the girl assures me that they are actually working on my order this time.
The bingsoo was good but definitely not the best I've ever had. Would I come back? Nope.
