After years of saving, you have finally done it\u2014you rented a space to open your very own coffee shop. You\u2019ve already painted the walls and set up the furniture. The next step is to plan your menu. In considering both taste and cost, you have developed a coffee flavor that is sure to bring customers coming back for more.<\/p>\n
