I've been to Parts and Labour both for dinner and for the night life while crawling Queen West with friends. We quite enjoyed the funky vibrations the dj was spinning - they make you wanna shake your tail feather! They also have a club in the basement which has a cover charge - but we never ventured that far.
The old hardware store atmosphere is really trendy and has a great vibe... for night life... but the beer hall tables were not much of a setting for a romantic dinner though. In my humble opinion, the prices were not reflected in the quality nor the portions of the food; though the service was great, my food was mildly flavored and not served hot.
