What is the diameter of a 7 square meter restaurant?

It is not appropriate to install chandeliers of any diameter in a 7-square-meter restaurant. It's too small. Put a ceiling lamp in the middle and four small spotlights in four corners, aim at the center of the dining table, and let your food be red, blue, green and distinct under bright lights. Color, fragrance and color come first. The ceiling lamp makes the restaurant very comfortable and in a good mood. This style is used in luxury hotel boxes to attract diners.
