Really limited seating so don't expect to be able to spontaneously visit and enjoy your pastry while seated if you're visiting at a busy hour. You definitely can call ahead to reserve, but not sure if that's only for their afternoon tea offering. Parking is on the street, but you can definitely park at the nearby Loblaw if you're quickly popping in and out.
However, the macarons and the pastries are amazing!! My favorite is the earl grey and the different variety of matchas.
