Been living out here 10 years now. I'd say Phil's BBQ, if you're in Carlsbad, go to the one in San Marcos, you won't regret it. Hike Torrey Pines (park in street near the golf course then walk down, do not go to the pay parking lot). Beach in Carlsbad Village is good or Moonlight beach in Encinitas. Pick your spot in Encinitas as there are tons of places to eat, Encinitas Ale House has a great burger and tons of beers to choose. Drive up to Mount Soledad, can see the entire city from there. Walk around La Jolla Village then go to El Pescador for a fish sandwich. Balboa park is great. North Park (hipster area) and Little Italy have some great places to eat. Basic Pizza downtown was started by a guy who copied Bar in New Haven. Fidel's in Solana Beach is great Mexican food. Padres actually have a team worth watching this year and a great stadium.
