If the dining room has a large space, it is more suitable for the dome. And if the restaurant is next to the living room, it is suggested that the ceiling shape of the restaurant should match the living room. Generally, rectangles are more common, but in the process of decoration, they are simpler.
If the dining room is connected to the living room and the dining table is rectangular, it will be more clear to divide the area with a square ceiling.
If you choose a "round and complete" round table according to the traditional family in China, it will be more appropriate to echo the dining environment with a round ceiling.
