Honestly nothing more than a gimmick. I would just genuinely avoid places like this unless you actually just into the gimmick itself.
Personally didn't find any value of coming here other than the fact that a few acquaintance of mine dragged me here the one time.
Food: Generic Bingsu that was quite over priced. Although it wasn't bad it was just generic dessert. Had the mango Bingsu and it was okay. Sweet with vanilla icecream and mango chunks on the side.
Service: Friendly staff, nothing out of the ordinary just your typical order taker type service.
Ambiance: Poop decoration everywhere.
Recommendation: Stay away from this place unless you want to pay in for the gimmick. Otherwise I don't see any redeeming qualities with over priced desserts and a concept that is dependent on the poop gimmick.
