No. Just as it would not be wrong to own a general stores and sell dairy, meat and fish products during Lent, or to work in McDonalds during Lent.
Fasting is a personal ascesis, and not one we can or should impose on others. It is not eating meat which is wrong, but being unable, as an orthodox Christian, to control ourselves.
There might be issues around tasting the food in a restaurant if one were a chef. Not sure how that would work.
