There is no Asian theme between Empress and Sheppard, which is the busier stretch (it's also the older, denser stretch and "downtown" North York while the area towards Finch is "uptown") because the street there is lined almost completely with office buildings or restaurants, and Mel Lastman Square, of course. But, as you say, this is all along one street - one block away, Doris and Beecroft are service roads lined with driveways and parkettes.
Mississauga's working with an area that's much larger, that's building on some greenfields rather than redeveloping individual sites within an established area, without a strip of relatively cohesive commercial buildings like Yonge, and with a mall. Strike one, two, three, and four? Maybe, maybe not...it really is too soon to tell.
