We've eaten at the Osington location twice. Both times it has exceeded our expectations with the quality of food and service. We had the lobster rolls as well as the lobster poutine (among other things). both times there were large lumps of delicious lobster meat in both and appeared recently shucked.
We could not have been more disappointed in the Queen east location. The lobster in both the rolls and poutine resembled something out of a can or had been shucked long ago left to soak in brine. The multitude of shell bits leads me to believe the former. They were flavourless and resembled a lobster mush. Not at all like our experience at the Osington location. The peel and eat shrimp shell was zippered, but the vein wasn't removed. Nothing less appealing than scraping poop out of the back of your appetizer.
If I had to guess, I'd say the kitchen in Leslieville cuts corners and therefore serves an inferior product to Osington, at least the times we went.
