I'm a huge fan of sweets especially if it's wrapped up pretty. Suite 88 Chocolatier in Montreal is one of the prettiest chocolate boutiques I've come across. Not only are they are open quite late, they also have their own gelato along with various chocolate treats. I stumbled upon Suite 88 after my dinner at Chu Chai and bought some truffles and chocolate bars.
