After my first week working in the area. I gotta give it to Mr. Tasty for being the cheapest lunch I've had to pay for... and filling too!
For Fat Friday, as coined by one of my coworkers, we took a short walk from the office and headed towards Nathan Philip Square. Mr. Tasty is there everyday even thru the winter. The medium poutine at $5.50 was very filling. I'll have to try the hotdogs/sausage another time - didn't want to go into a food coma at the office.
One of the ladies did make a good suggestion tho... they should have a half serving of fries or poutine so we could get a combo fries and sausage/hot dog for more variety.
Still... Mr. Tasty is a great option for straight forward un-fancified poutine or street meat.
There's another fry truck a few feet away, but you gotta go to Mr. Tasty... The name says it all ;)
