Dr. Brown's comes from the east coast and is supposedly a deli staple out there. There are several colors with a few themes: the diet versions have outlined text instead of solid tone, and there's a different New York landmark within each one.

Flavors: Diet Black Cherry, Black Cherry, Cel-Ray, Cream Soda, Diet Cream Soda, Root Beer, Ginger Ale.
