Personal opinion, best burger in San Diego is at Rocky's on Ingraham street.
Western Steak Burger on University Ave is pretty darn good too but points off for not having beer and being cash only.
Went here a few weeks ago by accident and it was great. Good food, good service, not too expensive, live music and that day the $5 crab cakes on the happy hour menu were as good as any I have ever had. South Park Bar and Grill San Diego Live Blues and Jazz Club
beer and pizza, all top quality.
BLIND LADY ALE HOUSE
My two favorites are Perry's, near Old Town San Diego Perry's Cafe - Loma Portal - San Diego, CA
and Tip Top Meats in Carlsbad. Tip Top Meats
