There was the best meal I have had at the restaurant last night.
【It 】was the best meal【that引导定语从句,做从句宾语,省略】 I have had at the restaurant last night.
其中it 是代词,代替the meal .
there 是副词,可用于【某处有某物】的固定句型.
句意：昨天晚上在餐馆所吃的那顿饭是我所吃过的最好的一顿饭.

当确定目标（这里是meal)的时候， 就用it, 这里it是形式主语， 不可以用there, 指当前的目标。中文的意思是， 它是或者这个是(best meal).
