I love Rockaberry's pies... They're consistently delicious, and there's always a huge variety.
Most people love the Oreo cheesecake and other chocolatey pies, but I'm not a big fan of chocolate (yeah I'm weird, I know)... My absolute favourite pie that I can't get enough of is the strawberry rhubarb crumb, warmed up. I often go in and pick up a slice to-go :)
The "regular meals" are also really good, and the prices can't be beat. The Soup / Sandwich / Pie combo is great.
The restaurant itself is nicely renovated from their recent move into the old Pizza Hut local and it's cozy and comfortable. Never too loud or crowded like the one on St Charles (Kirkland). I drive out of my way to this one even though I'm closer to the other 2 (Kirkland/Vaudreuil).
Oh, and if you're ever invited to a dinner, be a good host and pick up a pie at Rockaberry's to bring for dessert, would you? ;)
