The food could be the best they've ever had, but if they feel uncomfortable in the place they're eating it, chances are they'll trade for slightly less quality food at a restaurant they love being in. Here are the top three to avoid. Keep the music light, nothing that will overpower people's conversations. You want it to be a place people enjoying spending time.

Music, lighting, temperature — just the general atmosphere of your restaurant is incredibly important. Make sure the place is well lit enough that the patrons will be able to see what they're eating — and each other — but not so bright they feel like they're in a hospital food court. There's nothing teodoor about chintzy restaurant tables and chairs.

Do not, under any circumstances use fluorescent lighting. Cheap and tacky restaurant furniture. Adjust the heat or air conditioning accordingly to the weather. It doesn't have to be a trial, but keep in mind that there are plenty of mistakes to be made.

Decorating a restaurant isn't always easy, especially if you've never done so before.
