Food: Self-serve Froyo! So good! They offer many flavors and change them quite often. You can also choose waffle cookie (never tried, dunno the taste~) or add different toppings at the end~
Service: Self-serve stations, however the handles can have their little temperaments at times. The cashiers are most often young students, often disorganized when it comes to payment I mus say.
Price: Pay by weight, but beware the big bowls can lead to over-consumption hihi~ (they had smaller bowls before but removed now for some reasons... = ="
Ambiance: There are seats indoor (ye!), the ambiance is nice but the chairs are those cheap plastic chair and no staff to clean the tables... (if you offer a indoor seating, then maintain it, otherwise don't...)
