I lived just down the street from The Senator for 2 1/2 years when I 1st moved downtown but I never managed to get there until today. Based on my overall impression, I certainly wish I'd started going there a long time ago. The venue has been around since the late 1940's and not very surprisingly has the look, feel and layout of that 'era'. It also appears quite fresh and clean inside; I was with 3 others for brunch and it was fairly crowded while we were there and gradually became even more so before we left.
I ordered their breakfast sausage with (scrambled) eggs which also came with home fries, toast and baked beans. I found everything delicious and the service very prompt and friendly. The venue appears to be a great, convenient downtown location for a meal with a small group of people or by yourself, therefore I would also recommend it to those visiting Toronto - they offer a wide variety of fairly reasonably priced dishes.
