I just rediscovered my affinity for cheese. On Monday. I tried a little place on Yonge north of Briar Hill (whose name escapes me - help!)... I'm looking for other places in the north-central part of the city with great cheese. Yes, I'll go to Loblaws, which has a fair selection, but a place with a little more guidance is definitely worth the trip.
I've had the opposite experience at Whole Foods. I find that often their pre-cut cheeses are over-ripe, dried out and funky and their staff (while very friendly) don't really seem to know a lot about the products. Eg. I recently asked about a Quebec cheese (the name of which escapes me) and the sales clerk described it as a mild and creamy cheese. I bought it, and it turned out to be an extremely pungent cheese (I do like pungent cheeses, mind you, but it was totally different than what I thought I was getting).
rbc, I think the shop you referred to is Alex Farms, which also has a great shop on Bayview, south of Eglinton (and many other locations throughout the city). In that neighbourhood, there's also a shop on the southeast corner of Mt. Pleasant and Eglinton (Cheese Emporium??) though I've never had occasion to try it. Pusateri's has a nice selection (and I find the cheeses to be in better condition than those at Whole Foods), but you won't get much help from the staff.
Dont bother with whole foods - overpriced overpriced overpriced!!!
Go to Kensington market and head to Global Cheese - They have sooo many types of cheeses and let you taste everything before you buy.
Great prices too, sometimes you can get a deal amazing deals (got a half a wheel of amazing french brie for $6 last time)
I had a great experience at Alex Farms on the Danforth recently. They have a location on Bayview, south of Eglinton also.
Here's my recent thread which may help also: http://www.chowhound.com/topics/476091
All the cheeses were delicious, but the 5 Year Old Aged Gouda was the hit of the party - absolutely delicious.
