I stumbled upon this place after visiting my favourite restaurant in the city (Stoney's Bread Company) which is located directly across the street from Olive Fresco.
Olive Fresco is a highly specialized store that sells a large variety of olive oils and balsamic vinegars (I'd estimate 20+ of each). What's even more amazing about this store is that they have an actual tasting room for all of their olive oils and then another tasting room for all of their balsamic vinegars. The staff were very helpful in guiding me through the store, providing me with the backgrounds and uses for each product...as well as supplying me with tasting samples for each of their products.
For a person that loves to cook, this place is heaven on Earth! A call to all of the foodies out there...check this place out...it deserves your support!
