Sunday business brunch near Convention Centre?
Or short taxi ride away. Thuet is great but any other suggestions?
Niagara Cafe is a short taxi ride away. It is especially nice when you can sit on the patio. I recommend the eggs benedict.
Beerbistro is a short cab ride away (King and Yonge). Good food, great service and a suitably businessy atmosphere. Their main brunch menu is online (http://www.beerbistro.com/menus_brunc...) and they also serve some lunch stuff at brunch (mac n cheese, lobster taco, burger, etc.) for those who don't want breakfast food. They have a patio and the inside tends not to be crowded during brunch since they haven't been doing it very long.
