Lettieri was around before Starbucks invaded Toronto, which is, of course, way before the current indie coffee shop renaissance our fair city is undergoing. The Yorkville location is one of the last standing. A lot of them, including the Front street East one, have been converted to Hero Burger restaurants(same ownership).
The Cumberland avenue store brews good, if not memorable, lattes and espressi. They also have great lunch options, baked goods and smoothies. A great option when in Yorkville, whether shopping or chilling.
