My son and I were visiting Montreal in August.
My nephew who usually lives in Montreal recommended the Green Panther and I am glad he did. We were staying at the Hostel on Mackay and we visited the Green Panther location just up the street - very convenient for us.
My teenage son tends to sleep in so we ended up going there right when they opened at 11am (We would have gone there the night before for supper but the website said they were closed - an oversight that probably needs to be remedied).
Our brunch was excellent - falafel and juice. Good meal.
I found Montreal a little pricey and the Green Panther I also found pricey but if I lived in Montreal I would be there at least once a week.
