• serve soda in vintage-looking bottles: Drinks such as Coca-Cola were immensely popular in the 1920s, so selling retro glass bottles of soda stuffed in big buckets of ice will help to set the mood. Although I couldn’t find Coke in retro glass bottles, you can easily find that in other brands. Try natural sodas, sold at newfangled stores such as Cost Plus World Market. IBC also sells their root beer and cream soda in authentic-looking bottles. credit
