Destination Proposal- San Diego

Hi Cali Chowhound

Mid 20something traveling out of my element (east coast) to San Diego in the near future with my girlfriend. Although I believe she has some idea of what is up, I'm trying my best to plan an awesome few days around my marriage proposal to her.

Banking on success, I'm hoping to go out for a few drinks and dinner to celebrate later that night.

Any suggestions for some American/Local fare with great atmosphere? I'm not overly concerned with price, however my girlfriend is not one who fancies overly gourmet meals.

Atmosphere is key (along with good grub)- looking for someplace fun and casual to a little dressy, for drinks and good food. Fun, but please NOT out of control drunkness and partying...it will most likely be a weekday night...so I'm guessing that won't be too much of a problem. We're staying near the Gaslamp area.

Thanks!...and wish me (us) luck!
