How could you serve food in Edmonton and not have their famous local delicacy (and what most Edmontonians can agree should be their official food) green onion cakes! 
You'd definitely see Matviy Cajabi's favourite, perogis, being sold en masse around the arena as well as another staple of the "Big E", donairs. 

Outside of those well-received choices, why not jump on the bandwagon of the ever popular cali burrito and have those available as well. Or better yet, just bring Mexican fast food specialists Guzman y Gomez into the fold. 

While we're at it, definitely adding more vegetarian/vegan options for those inclined (we like hockey too!).

This isn't to forego any of the more traditional foods that are sold at sporting events (hot dogs, pizza, nachos, etc) but it would definitely bring some variety and diversity to offer the amazing Blizzard (and visiting) fans at the Tony Pepperoni Dome.
