I will be traveling through the park this summer and was trying to plan my food situation. I plan on eating at the waysides and camp stores but was wondering about the following:

Is there much of a selection of food at Lewis Mt Campground? Wayside type food? Mountain House/Alpine Type food?

What about at Thorton Gap/Panorama? Good enough for a couple of candy bars to get to Elkwallow Wayside? Is there a blackberry milk shake there?

Thanks
