The name is misleading: this isn't a deli, but a small cafeteria; and it's not in the pines, it's attached to Grand Canyon Lodge. But putting that aside, it serves takeaway salads and sandwiches to pack for a hike or picnic as well as pizza, soft-serve ice cream, and a handful of daily specials like chili and pulled pork.
The food isn't great, but it's convenient and relatively affordable.
