Recommendations for mixed age groups?

Traveling with our 19 yr old son, we are in our 40s, 50s, but young at heart! And our son loves to hang with us, we are more like friends! Where can we go that is a good place for mixed age groups? The only one I can think of is Senor Frog, which we will surely visit. Also, is the foam party only for the 20s crowd? We will be in Nuevo Vallarta and are also considering the club tour, can anybody make recommendations on any of this? Muchas gracias!!

Cafe Roma is a good place... they make a decent pizza, and the booze prices are really good. Friends of ours who live at Kite in Nuevo often stop in for the beer and pizza. It is not a place for entertainment (except for karioki night). But it is not a mixed age place.

Maragritas are cheaper at The Cheeky Monkey but you cannot beat the price of beer with pizza at Roma. Also ask about their private label tequila. It is very good.
