Toronto's chefs tend to avoid simplicity. If making a BLT, they'd rather smoke the bacon, toss in market-fresh arugula and drizzle lemon aioli atop a focaccia bun. After all, the best part of dining out is enjoying something you could never make yourself. Sandwiches, then, pose the perfect challenge; some may seem easy, but at these restaurants, they're utterly unique. [Stack of sandwiches at Rashers. Photo by Parisima Baha]
