I came here the other day with a group of girls from work. The service was very friendly and respectful of our time constraints. Being just the next block down from the North York subway stop, it makes it quick and convenient to get to.
I ordered the California Grilled Chicken Salad as I had had this once before at another location and honestly, it's about the only thing I like on their menu. It is a very good salad and I would definitely recommend it. I did feel however, that my chicken might have been a little undercooked... although I suffered no 'issues'.
Again though, it's the only thing I like on their menu so I think I would be more apt to go to Milestones which is right at the North York subway station than to walk down to Jack Astor's.
Their saving grace is definitely their service.
