Great place for breakfast - and very convenient if you are going to see a show a the Canon Theatre.
The atmosphere is fun - this place has been around for ages and it looks appropriately retro which just makes brunch all the more fun :)
On the note of brunch...Brunch at the Senator doesn't start until 11:30, before that you are restricted to the breakfast menu so beware. Also - the price of the "Senator breakfast" goes up by two dollars at 11:30. However, our great waiter made light of this and was willing to let us wait 15 minutes to order just on the border of 11:30 in case people at the table wanted both cheap breakfast and yummy brunch.
Side note for coffee drinkers - the waiter was happy to tell us that they make their own blend on site...but beware that if you order decaf it will be instant!! This isn't a big deal for me...but I know a lot of people who would be really disappointed with instant!
Overall - fun place with yummy food (true greasy spoon) so have fun - and be aware that you may have to wait for a table.
