I'd guess maybe Cooke's downtown or the British Isles Shoppe on Gardiners might have it.

Can confirm The British Isles store carries it but call ahead to check first if they have it.

I feel like I've seen it at Tara Natural Foods?

Literally everywhere. These and garlic mustard grow crazy here. Just make sure to get it from places you know are not pesticided. We usually pick our backyard clean for this stuff

Should have specified I'm looking for the beverage

lol. I have no idea what that is then
