Is there a conjunctive that's roughly equivalent to "in that case" or "if so"?


Say for example I want to say something like

> レストランに行きたいですか？行きたかったら、私は予約をしておきますよ。

It feels cumbersome to me to have to repeat the verb 行くin the second sentence.
Is there a conjunctive that I should use to replace the phrase いきたかったら? Does
場合は carry a similar connotation? Or is it just normal in Japanese to just
repeat the verb here?




"In that case" / "if so":

  * **なら** (colloquial)
  * **だったら** (colloquial)
  * **でしたら** (politely colloquial)
  * **であれば** (formal, bookish)

Much like だから or でも which you may know, the conjugated forms of the copula だ
can function as independent conjunctions (not conjunctive particles) at the
beginning of a sentence, referring to the context before. It may sound
surprising, but this is perfectly grammatical. The politeness or other nuances
all conform to normal grammar that you need to adjust to.
