Simple idea, executed well.  Ice cream, gelato and sorbet - we tried many different flavors - all were good.  We sat outside on a pleasant night with a nice breeze.  It was a great end to a nice evening.  Overall the best gelato / ice cream we found on our Montreal stay.  Only negative, one person working there allowed us to mix and match gelato and sorbet, etc, but another did not.  Other than that, highly recommended.
