la petite patisserie on King East
Had to mention this newly opened Patisserie on King East (just east of Sherbourne on the south side - in the same building as Subway). I just sampled their chocolate eclair and was very impressed. It's reminiscent of the type that you'll find at Le Duc de Lorraine in Montreal.
I've haven't had a chance to try anything else, but if the eclair is any indication of quality, I'm sure that I'll be suitably impressed. They have a nice array of pastries and the service was great.
If you're in the 'hood, I suggest that you check it out.
