I was there in December and my recollection is that the pastry shop was included in $100USD F&B credit. However, I did it as an adjunct to a few coffees in the lobby lounge. They had me go over to pick out what I wanted and let them know that I was having a coffee in the lounge and it all wound up on the same bill. I think room service might have also been included. I don't completely recall because I left pretty early in the morning for my flight but I believe it was all offset by the $100USD.

I enjoyed the hotel primarily because it's in the same district as my family so I can walk back and forth to visit and get out of there when I need some quiet time. After a particularly rowdy morning with the relatives, the lobby lounge felt like a sanctuary!
It's also pretty handy for the night market behind the hotel where I was able to get some great stinky tofu.

I wouldn't say it's dated, but it's evident that it's not brand new or state of the art. That said, the room was huge, the view of Taipei 101 was great, and the breakfast buffet was quite good. So, all in all, hit all the points I needed. I'll be back in a couple of weeks so if there are any specific questions, I can try to answer those by doing some in-person reconnaissance.
