I've been to the Crown and Dragon a bunch of times, always for wings and beer, but neglected to write a review until now. These are my favourite wings in the city for sure. Tuesday and Thursday are wing nights and Thursday is busier by far (last night it was about a half hour wait for a table for 2). It's a pretty small place and gets packed on wing nights (not sure what happens on non-wing-nights). The service is always very good and the wings are ready really fast, even when it's packed in there.
The wings here are BIG and they're nice and crunchy on the outside, not chewy. There's just the right amount of sauce and the meat is tender. They've got something like 30 flavours but I think the more classic ones are the best (buffalo, hot, honey garlic...) but I haven't met a wing there I didn't like. One thing to note is they won't pack up uneaten wings on wing night, so make sure your eyes aren't too much bigger than your stomach.
They have a special on pitchers of Canadian a few nights a week but it tasted watery and seemed like the carbonation was off so I wouldn't really recommend it (bonus: the waitress was totally gracious and took it back with no arguments).
They also have two decent dart boards and darts available from the bar if you ask but you pretty much have to choose between wing night and darts because otherwise it's too busy.
