I don’t think Piano Piano pizza is worth your time.
Would you be interested in trying old school Toronto/ Mississauga type pizza? Mississauga does have an Italian population and some good old fashioned Italian bakeries. I am sure they also have some old school pizzerias. I confess, I rarely dine in Mississauga, so I don’t know which pizzerias are their best.
We do have this Mississauga thread
Mississauga’s looking to be the next Scarborough-style food destination
Also, this Greek / Turkish/ Balkan thread
Greek, Balkan and/or Turkish restaurants, bars, coffee shops, groceries and bakeries in Toronto and the Greater Toronto Area [Danforth] [Scarborough] [Ossington]
Toronto and the Greater TO Area are having a Turkish restaurant and gourmet shop boom. Anatolia is the oldest, and it’s quite a good restaurants near the border between Etobicoke and Mississauga. I had takeout about 2 years ago.
In terms of shopping, Sherway Gardens, which is close to Mississauga, is a much nicer mall than the Eaton Centre. It has a new Eataly, and more upscale shops than the Eaton Centre. Free parking, too.
In terms of some regional Chinese food that might be of interest, there are some Uyghur restaurants in Mississauga. One of those has caught my attention.
