If you want to pay too much, Il Fornaio is your best bet, but you're not going to beat Parioli.

As for adult stores, you'll have to travel to get there. The adult emporium off convoy is probably the most uber-able for you, just go during the daytime.

Del Martians....

The only Italian restaurant in Del Mar I can think of is Il Fornaio.  Right on 15th street and coast highway on the upper floor of the center there never personally eaten there but has good reviews.  Nice view for evening cocktails which I have done there.  Other places worth of trying in that same area would be Sibicca and Cafe Secret (Peruvian).  If you're willing to travel north, Encinitas has a favorite of mine, Trattori i Trulli...

As for adult stores, you're kinda limited in this hood.  The uptight bourgeois north county folk won't stand for that kind of fun!!  You kind of have to go up to Oceanside, Romantix or Deja Vu Love Boutique or down south to Convoy area Adult Emporium or even further south toward Hillcrest and downtown.

Best of luck and enjoy my neck of the woods!

Bencotto is molto bene.

Have eaten at Il Fornaio many times, and take family there for Christmas Eve dinner. Food and service very good, and nice view if you get there and sit on patio at sunset or at lunchtime.

the best adult store around is the Barnette Avenue Adult Superstore...

I love this store!  It's way bigger than most.  The merchandise is great, there's a couple of theaters, and there is live entertainment (on the weekends at least)

Del Mar has awesome restaurants no adult stores.
