We all live very active and busy lives. Any feature that a home plan might have that can make our lives simple is always a plus. An eating bar offers an amazing amount of convenience and versatility to a home plan.
While a breakfast nook, or breakfast area if you prefer, is a great feature it can sometimes be too formal for those days when you are on the run. An eating bar offers features that a breakfast nook just cannot. The first is location. You cannot get closer to where the food is than being in the kitchen. And when you are done eating, your dishes are already in the area where they will be washed.
Many people who have an eating bar end up converting their breakfast area into a sitting and relaxing space. They find that the eating bar can satisfy all their daily needs for a place for the family to sit and eat together. Which in a way, makes the eating bar a tool in expanding the "livable" area in your home.
