This is not my usual Starbucks, but I was in the neighbourhood, so I stopped in for breakfast.
Decent size with adequate seating and decor of a typical Starbucks franchise. This location has a handful of small tables, some leather chairs, one large communal wooden table and offered a few tables and chairs outside.
Staff was friendly, fast and efficient like most Starbucks, so I will definitely come back if I'm in the area again. Plus this location is really close to the St. Lawrence Market and not as busy like the one situated across from the market, so it may be worth the extra block east of Jarvis if you want some peace.
