Beitou District, Taipei City｜Emperor Spa

All in one shop for dinner, hot spring and karaoke (if you have a private room booked). Good venue for 10-18 people gathering. No complaints with the food. You can have private family room for hot spring. Some might find the eggy odor smelly due to the natural sulfur compound, I am biased and found the odor positive. Commute wise - Plenty of Uber when I checked at around 10:30pm.

This is a natural hot spring Onsen in Beitou containing traces of Radium which is supposed to be extremely good for skin and health. It is exactly what you expect from Japanese Onsen and only nude bathing is allowed (no swimmers trunks). The dishes are delicious and if you order the food, the fees for use of Onsen is waived. I recommend this place for ardent Onsen lovers. Your skin will feel very soft and smooth after soaking. They recommend that you don’t wash off the Onsen water and just towel dry to achieve the best results.

Comfortable, easy to access via transit and the food here is pretty good. The ambience of the spa is quite nice, and there are different pools of temperatures from cold, up to 42°C. The central pool temperature are marked. There's also a laydown pool, "massage jets" in some cool pools, and both a steam room and sauna. You can rent towels, and the pools we went to (#1) were nude/separated by gender. I believe #2 is unisex with bathing trunks, and I'm not sure what #3 is like. There are a variety of veggie items at the restaurant, although we got some meat dishes as well. The portion sizes are quite good too.
