Pretty good actually! The bagel sandwiches are rather good - I got the vegetarian one and the veggies were tastily roasted, though the cheese were less so.
I also got the yogurt. The fruit definitely tasted like it was defrosted from frozen fruit, which was disappointing. The granola also seemed to have corn flakes or something in it that was less than exciting.
I'd say it's good enough for a quick bite, as long as you're not expecting a fresh St-Viateur Bagel. But probably don't get the yogurt!
