Old Port is a pleasant place to visit and walk through, full of eateries, historical sights, and locals and tourists alike. It's nothing out of the ordinary, so if you've never been, you might have a better time heading up to Mont Royal and checking out the park. If you're a local, or have time to kill, why not check out Old Port? Get yourself a nice book and relax.
We saw a random event going on where folks were passing one another boxes in a long line - never quite figured that out.
