I dunno about missisauga, but my mom always goes to down town toronto to listen to huge pharmicutical companies pitch there drugs to her, and shes always on like the top floors of the big bank buildings downtown. That probably doesnt help though…
If Toronto is too far go to Oliver & Bonacinis the new one in Oakville (QEW and Trafalgar), that’s not too far from Mississauga! You won’t have to fight through traffic and all.
If you want fine italian dining try Via Allegro. It’s right across the street from Sherway Gardens. I took my g/f there last NYE. Really upscale and the food was awsome. Great wine selection too. Search google I bet there are reviews somewhere. I always get the pasta because it’s homemade and tastes amazing.
