Bottomless mimosas are a popular drink option for brunches and other events. They are typically made with champagne and orange juice, and the term "bottomless" refers to the fact that the drink is served in an unlimited quantity for a set price. The idea of bottomless mimosas is to create a fun and festive atmosphere where guests can enjoy the drink without worrying about running out. However, it is important to note that bottomless mimosas are not always made with actual champagne, and the quality of the drink can vary depending on the establishment. Additionally, it is worth noting that in some states, such as Michigan, bottomless mimosas are illegal due to laws prohibiting free refills on alcoholic beverages. Overall, bottomless mimosas are a popular drink option for brunches and other events, but it is important to be aware of the quality of the drink and any relevant laws or regulations.
