Maybe it’s because our summers are short that all Ottawa citizens flock to restaurant patios as soon as the snow melts, and stay till it falls again. Some eateries plop down a couple of tables just about anywhere outside, abutting busy roadways where they snarl sidewalk traffic. But we’ve found great al fresco dining – from gourmet fare to burgers ‘n’ beer – that eliminates both sunstroke and exhaust fumes.
