Can a restaurant chairs layout be boring? I think it can. Most restaurants mix their chairs and tables around. There will be a two place setting here, a four place setting there and perhaps even a six place setting over there. What they don’t have is a predetermined chair layout that looks military or makes one feel like they are back at school.
I am sure you have come across this type of layout. The tables all lined up facing exactly the same way. The chairs, too, are also placed exactly the same. some will say that this is a formal style of dining. For a banquet - perhaps, for every day dining, no way.
As a diner, if, and it’s a big if, I do eat at a restaurant that has that military style dining experience, I feel lost in a crowd. I am no longer important. Other restaurants that turn tables at angles to each other create an island effect. My table is my island and the wait person is there to help me.
By being a little flexible with your restaurant chairs layout, you can provide your diners with a more satisfying experience. Will you lose out on a couple of tables - perhaps. But then, would your rather have 50 tables with no customers, or 40 tables that are all full? - all because you put a little thought into your restaurant chairs layout!
