Actually, you should be eating California Burritos or Carne Asada Fries wearing flip flops & sun glasses every where you go...now you're a San Diegan
Well there are a lot of nice clubs, restaurants, bars, etc.. depending on what you guys are into. If you can't decide on what to do, go to signonsandiego.com I've lived here all my life and even I use their site. If you wanna be a tourist check out Sea World, SD Zoo, Old Town, Embarcadero Park, Belmont Park, La Jolla Cove & Downtown La Jolla, Coronado, for beaches I recommend Del Mar area.
