Which could be better one outside or at home?

There was a neighbhour boy who a few years ago asked my wife for a dinner night out for which she replied that he was very young and not old enough. My wife called me up today and said the boy was back home after many years (now a well grownup adult). He called her over phone and asked for a dinner nightout tonight. She had agreed amd prefered one at our home but he insisted an place outside.Which could be better one outside or at home?
