It looks like it belongs in a Disney Theme Park, so you might be excused for thinking that you've somehow wandered into DISNEYLAND.
The Tam O' Shanter, however, opened 30 years before DISNEYLAND and is thirty five miles north. It does play a part in the park's history, however. It was Walt Disney's favorite restaurant and a favored haunt of Disney animators back when the Hyperion Studio was nearby. It remained a favored lunch location when the studio moved to Burbank but really became a Disney hangout when Walt Disney located Imagineering nearby.
Over lunches of prime rib and generously carved sandwiches served by costumed waiters and waitresses, Walt and the Imagineers planned out his Magic Kingdom. Doubtless the elaborately themed dining rooms rubbed off on Mr. Disney and his team as they designed DISNEYLAND.
You can still enjoy the same hearty meals in the same location on Los Feliz Boulevard. If the walls of this establishment could talk, they'd probably have quite a lot of interesting things to say.
