Exit 186 is Wellington Road. Take that north to Southdale Road. (fifth light, I think-probably 3 km), and then west (left for those of us map-challenged people) along Southdale until just about Wharncliffe (which is the 6th light). Right onto "Old Wharncliffe Road" (I never knew!)
If you live west of London, you could get off at Exit 183. Go north along Wonderland, (4-5km), (look for the landmark, Krispie Kreme which is pretty much on the corner of Wonderland and Southdale), turn right-east-onto Southdale Road until you cross Wharncliffe (4-5 km) and then hang a left into Tiger Jack's.
Looking forward to it!
