it is just a coincidence. Literally, “餐” means food, meal. “厅” means hall. “餐厅” means a place for eating.

i think Jiyuan is right. 餐厅 is a exotic vocabulary. in Mandarin we alway say : 餐馆/饭店/餐厅/酒楼, those are same meaning. don't worry, you can pick it up and use it in life time.

I think it‘s a coincidence，餐厅 literally means dining hall
