・chain store
・chain restaurant

連鎖店是chain store/chain restaurant。

零售連鎖店是retail chain。

That restaurant is a chain and you can find it anywhere, so you should try to find it and go there once.
『那家店是隨處可見的連鎖店，你應該去試試看。』

It is a chain restaurant, but it is always popular because the food here is really good.
『雖然是連鎖餐廳，但這家餐廳的餐點真的很好吃，一直很受歡迎。』

希望能幫助到你。
