The Friendly Dolphin near the old port is always consistent.
Whatever you do, don't go to the "New Mexican" place on the road out to Las Conchas. Our group went last year and it wasn't good.
Manny's is ok too.
Honestly, my favorite thing is to grab a couple of tacos from one of the little shops near old port/shopping area. They're always nice and fresh.
I'm hoping some of these mega condo resorts bring with them some decent restaurants.
