3.5 stars. I visited this store last week and had the banh mi croissant sandwich for lunch. This is a well-designed but tiny store just west of Dundas Square. No seating at all, takeout only!
The sandwich was really good. I didn't get a lot of traditional banh mi flavours but the porchetta was juicy and I enjoyed the pickled veggies on top. Would be 4 stars but the portion was tiny and expensive. Over $10 for a sandwich and coffee, which would be fine if the sandwich wasn't snack-sized.
Pastries looked good and I'll probably come back to try them at some point.
