No, on non busy days you can even just walk in. I do recommend reservations though.

No. Just recommend a reservation on busy days.
You're free to eat here with stressing at the inn. I will advise if you are walking the park's hiking trail, keep note of your reservation time, if you get one. It's easy to miss your time in the busy season.
