From Disney University Food Showmanship Disney Style 1973:
Built in the style of a typical North Woods lodge, the Hungry Bear Restaurant is probably the only place in the world where a person can watch a moose grazing along a river, canoes setting out with hearty explorers, or a majestic stern wheeler plying its way up the Rivers of America. This entire panorama can be seen from the dining terrace where guests may select from such "Bear Necessities" as Paul Bunyan hamburgers and Klondike corn dogs.

From Steve Birnbaum brings you the best of Disneyland 1982:
This is an immense place, yet when you sit on the ground-level veranda, with the Rivers of America lapping so close to your feet that you could cool your toes on a hot day, the activity of the rest of the park seems miles away. Ducks dive for occasional tidbits floating by, canoeists paddle alongside in Davy Crockett's Explorer Canoes, the Mark Twain towers above you as it steams downstream, and the air rifles in Tom Sawyer Island's Fort Wilderness (just opposite) are tap-tap-tapping away. There's com- motion all around, but you're strangely (and quite pleasantly) removed from it all. Better yet, in busy periods, the restaurant's crowds begin to build up a little later than they do at more centrally located establishments, and they also thin out a little earlier. The menu includes hamburgers, cheeseburgers (topped with Canadian bacon if you like), hot dogs and corn dogs, french fries and fried onion rings, fried chicken filets, and beef-and-cheese, ham- and-cheese, and tuna sandwiches plus chef's salads, fruit and cottage cheese salads, tuna salads, and an array of sweets (turnovers, brownies, ice cream bars and sandwiches, frozen bananas, and the like). Presented by Wonder Bread. Serves Lunch, Dinner, Snacks.

2011 added Fried Green Tomato sandwich to the menu
