Boom is for breakfast not for brunch. Starving Artist is for hipsters, Emma's is for yuppies, and Boom is for swilling two coffees and skimming the front page while lamenting that had there been any pea meal in the house you could have made this breakfast at home.
Fast, moderately filling, and slightly overpriced, the portions are always a bit stingy and the food never better than average. Boom will survive as long as the stretch between Dufferin and Bathurst lacks a Vesta Lunch equivalent.
