I'm a relatively new arrival to T.O., but Bayview from Davisville to a couple of blocks north is a superb foodie place:
Whitehouse Meats (top-notch butcher - almost always have buffalo meat, pheasant, venison and ostrich in stock, plus a vast array of the usual chopped up cows pigs & sheep)
Alex Farms (tremendous cheesemonger, also a small selection of deli stuff - this staff has the friendliest and most engaging staff. Try to escape without being forced to sample 'just a few cheeses', I've never managed!)
Fat Man Pizzeria & Buffet (does damn fine pizzas as well as an all-you-can-eat middle eastern buffet; not as good as the pizzas though)
Diner 55 (nice, friendly small diner, serves the usual standard fare at the counter or at tables - I personally found the food good but not exceptional, but it did very well in the Toronto.com '10 best' voting)
Duff's (again a '10 best' fave for their chicken wings, go all the way up to Armageddon strength)
Satay on the Road (Thai/Malay, one of the few places I've found in town doing Malay food so far. If anyone knows a really good authentic Malaysian or Indonesian restaurant please let me know!)
Also many other food places I've yet to visit, so won't comment on;-)
There are also a few interesting wee shops on the street. You can easily spend a couple of hours puttering about this area, and Mount Pleasant is an easy saunter away - which has a huge number of second-hand book shops, many with large and ecelctic cookbook selections.
Hope some of you find this useful. I stumbled on the area because our bank happens to be there, and no-one I've met in T.O. yet seems to have heard about it.
