Well, as with all offers to the public, the precise details of the offer have to be made clear and communicated unambiguously. Presumably, this offer is not for people who physically arrive at the restaurant and, if there is an empty table, ask to reserve that table for just 5 minutes in order to qualify for the discount? In that case it needs to be stated that the offer is for phone and internet bookings. You might also add '....made at least 2 hours prior to the booked time.'
大衆向けのプロモーションは、プロモーション内容の正確な情報を明確に伝えなくてはなりません。おそらく、レストランまで足を運ぶお客さん向けではなく、空いているテーブルがあれば5分前に予約すれば良いということでもないですよね？もし、そういうことであれば、このプロモーションが電話やインターネット予約のみに適用することに触れた方が良いと思います。それから、例えば、"made at least 2 hours prior to the booked time"（最低2時間前に要予約）というような詳細を付け加えると良いかもしれませんね。
