Will many people be visiting Naeso Temple in Buan and Naejangsan Mountain in Jeongeup?

When I went to Naejangsan Mountain at the end of October, they hadn't restricted vehicle access yet,
so I was able to drive all the way inside and enjoy the view.
But since the autumn foliage is supposedly at its peak this week,
I have a feeling it'll be crowded even if I go tomorrow, haha.
Naeso Temple might be a bit less crowded, but I'm not sure.
If you don't mind me asking, price isn't an issue, but
I'm looking for a good sashimi restaurant or
a Hanjeongsik (traditional Korean course meal) place, but I'm having trouble finding one. Haha.
I am a local from this area, but I still don't know it very well lol.
