When traveling in Yellowstone it's always a good idea to bring along a cooler—that way you can carry some snacks and lunch items for a picnic or break and not have to worry about making it to one of the more developed areas of the park, where all restaurants and cafeterias are managed by two competing companies (Xanterra and Delaware North). Generally you'll find burgers and sandwiches at cafeterias
and full meals at restaurants. The entrée selection includes beef and chicken, game meats such as elk and bison, fish like salmon and trout, and there are kids-oriented offerings. At the several delis and general stores you can purchase picnic items, snacks, sandwiches, and desserts like fudge and ice cream. Considering the park's remoteness, the selection and quality are above average, but expect to pay more as well. Reservations are needed for dinner at the Old Faithful Inn, Lake Yellowstone Hotel, and Grant Village dining rooms; during the summer reservations are recommended for all dining rooms.
