What do people do for dinner in the park? Staying at Lake Yellowstone hotel

We are camping for 4 nights in the Tetons and then for a bit of luxury we are staying at Lake Yellowstone hotel for 3 nights. Are most people staying at the hotel going out to a picnic area and cooking dinner at night?
We made 1 reservation at the dining room but it looks somewhat upscale and a little pricey, can’t imagine they are serving the full hotel every night and there aren’t many dining options. Curious what most folks who stay there are doing for dinner.
