Although there is only one employee, you may have to wait if you buy in large quantities, but the store provides a phone and line for ordering in advance.
As for the drinks, the whole glass of mung bean paste is filled to the brim. It seems to be mostly mung bean paste with a little crushed ice at most. When drinking, the mung bean paste is the majority and is very thick, so you need to suck it with a little force.
Recommended to everyone who wants to drink a drink but also wants to drink healthier.
