Wow- I am already tired and you haven't even left yet.

Re: San Diego-

You don't say who you are traveling with or ages- would really help to suggest a place to eat and type of food.

San Diego is more than Balboa Park and the Zoo, but it is a great start .

The Zoo can be an all day deal with food too. (Albert's is a good restaurant in the zoo.) There is a great restaurant in Balboa Park called the Prado. Bertrands at Mr. A's is fabulous and near downtown (but spendy too).

Day of week? Can make a difference as to where to recommend to eat as well. As does budget.

If you want to be near the water and are willing to drive, the restaurant at the Shores Hotel in La Jolla is smack on the beach, offers 3 hours of free underground parking and the food is very well priced. Best value for on the water dining in town.

There are a gazillion restaurants downtown and many of them are really good. Searsucker is very hip (reservations a must). I really like the Top of the Market at the Fish Market. Downstairs is good too, but upstairs is fine dining (with prices to match).

Give me more info and I can help further.
