The California chain, which touts itself as preparing quality burgers the old-fashioned way, without freezing, packaging or processing, is set to dole out a limited number of the famed patties from 11 a.m. to 3 p.m. outside Italian restaurant Osteria dei Ganzi on Jarvis Street.
Blog TO said choices would include three of their signature offerings: double-double burgers (two patties and two slices of cheese), animal-style burgers (with a patty cooked in yellow mustard), and a protein-style version (served in a lettuce wrap instead of a bun).
Jesse Wente, director of film program at TIFF Bell Lightbox, tweeted, "The news of an In-and-Out Burger pop up in Toronto tomorrow has thrown my schedule into complete disarray," while another Twitter user lamented that she couldn't go, saying: "I feel like my heart has been ripped out and stomped on."
The Globe and Mail reported that In-N-Out Burger has been hosting pop-ups around the world since December 2011 and has been at the Langley Good Times Cruise-In auto show in British Columbia.
The chain of fast-food restaurants, founded in 1948 by Harry Snyder and his wife Esther in Baldwin Park, Calif., has about 300 locations in California, Arizona, Nevada, Texas and Utah.
