<p>I said that my dad was a "family restaurant owner" and that my mom was the co-owner.</p>
<p>And apparently, this is wrong because "family restaurant" implies something along the lines of big famous chains like "Friendly's family restaurant"</p>
<p>rather than a small little restaurant run by a family.</p>
<p>Family restaurant just implies that it's a restaurant the whole family can go to (nice, friendly, clean, no strippers, etc.). It doesn't imply that it's necessarily part of a chain.</p>
