Diet cranberry juice at bars

Do most bars carry diet cranberry juice? I'm talking about dive bars, or chains like fridays/applebees.. Does anyone know? I'm trying to come off of diet soda's.. Since the only time I even like diet soda is mixed with liquor switching to diet cranberry is a good start, but have no idea if it is normal. I love club soda and vodka or tequila with lime but need to switch it up when going out.
