1. What place is the best place in Taiwan?
2. Where is the best place in Taiwan?
#1 is correct. Is #2 also acceptable?

Sentence number one is grammatically correct but repetitive. In order to avoid repeating the word 'place', I'd suggest:

What is the best place in Taiwan?

Your second example is also acceptable.
