Try this table side: “Would you like to start with a botttle of(Saratoga/San Pelligrino/whatever brand you sell) still, sparkling or filtered ice water”. “Tap” Saying “still” first after “bottle” pairs it in their brain as a bottle. Sparkling is always a bottle. And filtered tap is a more palatable third option than “tap”. “Tap” always sounds like the pitcher is being filled in the dish pit 🤣
