The Red House is super-cute. I see tons of people coming here to get a picture in front of the building, but there's also a good amount of stuff to do within and outside the Red House.
For the most part, it's shopping and eating (I have no problems with either of these!), and there are lots of cute shops within the Red House. There are, on occasion, events that are occurring inside/outside the building, which means more food and more shopping.
The shops are cute, and the merchandise they sell are pretty quintessentially Taiwanese. Some of the prices can be a little "yikes", but some of the souvenirs you can't find too easily elsewhere (e.g., a specific artist's showcasing).
It's not a humongous building, so there's a point in time where you'll either be done shopping, and you're too full to eat. But it's not really a place to stay at; you're honestly supposed to be milling around a bit, and then go to the next attraction point.
Is the Red House worth a very special, specific visit if you're coming in from outside of Taiwan? No. Is it worth it if you're already in Ximending? Maybe.
May be back, but only mainly if I'm in the area again.
