There are 3 locations of the Pump in Mississauga: The Clarkson Pump, The Port Credit Pump and I can't remember the name of the new one. each location has a great local pub feel, and no mater what day you go there will always be regulars around the bar joking with the bartenders and wait staff.
I find the portions to be very generous! Yesterday I had a craving for a burger so dropped in for the banquet burger which comes topped with bacon and cheddar cheese....and they are not stingy! In fact I only had a salad and raspberries for dinner at home later because my lunch was so filling.
I meet with my Mississauga friends at different locations so expect more reviews and photos now that I am using Yelp :)
Also.....there is a very good size patio at the Clarkson location and the Port Credit location which has been around forever as well has expanded I'm size pretty significantly, plus there is the new location a mere 10 minutes away. Success breeds success!
