Will be attending a large conference at the convention center with my husband at the end of July. We'll have a few business dinners, and dinner with another couple who also enjoy good food. We spouses will also have some free time for lunches and breakfasts. We love local cuisine, loath most chains, like seafood (but not sushi) don't mind spending money on really good food, but wouldn't pass up an exceptional greasy spoon either. We are staying at the Hilton near the convention center. Not sure if we will have a car yet. I haven't been in San Diego in 25 years, so I am open to anything. Suggestions?
