I choose to meditate in this moment.

some meditate in monestrys some in a zendo or a place where they peacefully and seriously do meditation and some meditate in any place they want even in their home so you need not go anywhere to meditate you can meditate wherever you are however you are.

He would always meditate before dinner.

First thing is that it is not compulsory to meditate in Islam but there is no such rule that Muslims should not meditate. Meditation can done at any place there is no specific place for meditation, You can meditate in home, work(when you are free), or any where else.
