Peel Pub was...ok. We went the Friday we arrived in Montreal and it was full to the gills with extremely young, extremely overdressed (I assume they were stopping in before going to the clubs...I hope, anyway) patrons who quite literally made us feel like old, frumpy nuns. The service, however, was good, the drinks cheap, and the food good pub grub (more poutine, please).
We returned two nights later, on a Sunday evening, to a much more low-key atmosphere, with everyone dressed down, some watching various sporting events, and just generally hanging out and enjoying themselves. We took full advantage of the inexpensive shots, and a few more rounds besides that and our bill was still very reasonable.
Not a destination by any means, but a good place to relax and have some cheap food and drink.
