Used to LOVE New York Seltzer growing up. They sold em in the snack bar in Jr. HIgh. It's been decades since I had one. Got one out of a Vendo at work the other. Doesn't taste the same to me. Tasted kinda cough-mediciney. I actually hated it.
Now, Clearly Canadian was another really good one. I liked it better than NYS, even back then. but I cant seem to find it in stores any more. You get a chance try it, just the right balance of sweet, carbonation, and quenching power.
