There's lots of Louis wings joints around the city...and they're probably okay. But I really like the outdoor patio on Yonge. I've been here 5 or 6 times and love it...nice staff and chilled out vibe. An easy spot to while away a few hours in the sun over a decently priced beer.
The poutine here is excellent: with the pork variety just tipping the fried chicken. The burgers are good too: keep in mind, eating in Louis' is a carb fest.
