The Toronto Argonauts and Calgary Stampeders aren’t the only ones gearing up for the 100th Grey Cup final on Sunday.

Restaurants and sports bars across the GTA are calling in extra staff and doubling up on beer and food to prepare for the big day.

“We think it’s gonna be really, really big,” said Tina Kalogeropoulos, national marketing manager at Pizza Pizza, the official pie of the Argos and the 100th Grey Cup Festival.

“We expect a huge increase in pizza and wing sales.”

Kalogeropoulos said whether fans are watching from home or going to the game at the Rogers Centre, Pizza Pizza will have the field covered, so to speak, with more food, staff and pop-up stands downtown.

Chris Bielecki, owner of the St. Louis Bar & Grill across from the Rogers Centre, said his restaurant has already started ramping up and he expects to be busier than usual over the next few days.

“This is probably the biggest event of the year for us,” he said.

“It’s all hands on deck.”

As is usually the case when any sports event happens at the Rogers Centre, Bielecki has increased staff by 50 per cent and doubled his beer and food inventory over the next few days.

And special to the 100th Grey Cup, St. Louis will be giving out plastic CFL football mugs with orders of Molson Canadian and Coors Light, on tap.

Even Duff’s Famous Wings on the other end of the GTA in Vaughan expects more takeout orders from home parties in the area on Sunday.

“We’re kind of treating it like a mini Super Bowl,” said Loren Erlich, manager of the Rutherford Marketplace restaurant.

The branch will be “staffing up a little” — with an extra cook, bartender, busboy and server — and has ordered an extra couple hundred of pounds of wings to handle the estimated 50 per cent increase in business.

The 100th Grey Cup final kicks off at 6:30 p.m. Sunday at Rogers Centre.
