My husband is going to be traveling for business this week in San Diego and needs some recommendations for good places to eat. He will be staying at a hotel on Shelter Island Drive, so not too far from that. Sushi, good Mexican, Italian, and places for breakfast would all be really helpful. Probably not interested in extra fancy dining as there won't be a lot of time for it. Also, if there is some place that you think can't be missed, that would be good too. Thanks so much!
