Stopped by while on a vacation in Toronto. Staff was friendly and relaxed, and the place had this retro thing going on...not in a kitchy sort of way, but in a "half-assed-but-still-pulling-it-off" sort-of way.
The Senator was fairly busy when we stopped in, but there was plenty of room at the counter for the bf and I to sit. The food is good enough to satisfy, but not so good that my inner-foodie celebration-alarm goes off. I had the french toast (decently yummy), and the bf had one of their basic eggs/toast/home fries plates. He liked it enough to consider going back there another morning.
The free WiFi is nice if you need it.
Definitely worth a visit if you're looking for a dependable-y good breakfast.
