I had dinner here tonight. I agree with much of what is said already. It's a serve yourself buffet. Cost was twd 200. One of the dishes contained egg.
I'm not sure if things have changed since the previous review. There's an area for taking dishes and cutlery to for after eating. There's different areas to separate plates, bowls and cutlery and also food and non food waste goes separately. There's no indication though that customers are expected to wash up.
The place is very nice and clean. It's a big building. I'm unsure as to whether or not this is a converted church building or if the building design has been made to make it have some sort of similarity to a church.
