The restaurants around Sun Moon Lake seem to close quite early. The restaurant I originally planned to eat at was already closed, so I ended up going to the restaurant mentioned by the owner of the B&B - Sun Moon Restaurant.

It's a type of stir-fry restaurant that offers set meals at different price points or à la carte dishes. Since there were only two of us, we chose à la carte and ordered:
The Hakka oil chicken leg was quite tender, and the bamboo tube rice was a bit small in portion. The flavors were okay. As someone who dislikes vegetables, I only sampled the Shuzi Mountain fern and the fried Japanese coriander, and I thought the fried Japanese coriander was quite nice when it was crispy. My friend, who loves vegetables, preferred the Shuzi Mountain fern.
What I was most looking forward to were the passion fruit shrimp balls. The shrimp was fried well, but it felt like the passion fruit was just a companion rather than being blended together; I initially thought it would have a more integrated flavor, but the combination of passion fruit and shrimp balls did work flavor-wise.
Finally, we were served some complimentary fruit - pineapple, which was sweet.

The dining environment was nice, and the presentation was thoughtful. Except for the bamboo tube rice being on the smaller side, the portion sizes of the other dishes were sufficient. There was parking available next to the restaurant, making it driver-friendly.
