Comments on Accessibility:
The entrance is somewhat difficult to maneuver through, but manageable. The bathroom is as close to perfect as is humanly possible. The tables can accommodate wheelchairs well. Grizzly Peak is designed with wheelchair users in mind. (The waiter even offered my service dog a drink.)
General non-accessibility information:
Grizzly Peak has very friendly and accommodating staff, micro-brews it own beer and root-beer and has great bar-food for anyone who wants a bite to eat.
