The food scene is consistently improving here, and there are far more places to eat, snack, and drink than any visitor will likely have time to check out on one trip. Definitely prioritize breakfast and trail and car nibbles from Persephone Bakery (its berry muffins are beyond), Café Genevieve (chicken and waffles), and The Bunnery (granola). Dornan's in Moose makes excellent sandwiches, which can be ordered ahead of time and picked up on the way to the parks. Pick up Local Butcher sausages if your accommodations have a grill. Lotus Café's "wellness cuisine" should satisfy even the pickiest vegans or vegetarians.
It is easy to avoid chain dining and instead support locally owned and loved businesses like Trio and Big Hole BBQ. Fine Dining Restaurant Group has cultivated a mini empire that includes restaurants like French-American Rendezvous Bistro and Italian small-plates Enoteca, wine bar Bin 22, specialty grocers like Bodega, ice cream maker Cream + Sugar, and a new craft meats retail line called Bovine + Swine.
