Yes, if I were to drink a bit of Lillet I’d definitely cut it with fizzy water as I tend to avoid concentrated sugar in general (soft teeth). Yes, of course I know alcohol metabolizes as sugar; that is one of the reasons not to drink too much. I do like some dry sherries, though I find they can be too harsh.
The closing of the Pointe St-Charles SAQ was infuriating. It had been there for many years, and was closed just as food businesses were starting to take off in that neighbourhood and there were more residents who’d want something beyond supermarket beer or wine. It was not running at a loss either. Very poor longterm business decision, and put the lie to their claims of sustainability, which would certainly include consumers in urban areas being able to walk to an outlet.
The outlet you are talking about (very high-end) is actually an SAQ Signature. The closest Sélection to it is the one on boulevard de Maisonneuve a bit farther east.
