There’s a cafe I go to every couple of weeks. With its new “buffet,” it has become even more attractive. NT$168 for all you want to eat, until 8 p.m. I don’t remember if the offer is also good on weekends. The selection – other than for pastries – is not particularly wide. But for the price it’s a very good deal.
I don’t know the street address. If you take the MRT, get off at the Chunghsiao-Hsinsheng station and take the exit for the park. Walk along the street to your right (perpendicular to Zhongxiao East Road). The Cafe et Boulangerie will be on the right.
