Cardiff,
Donovan’s is the standard in SD. I’ll be eating there this week with a friend;)

If you want a great steak to grill yourself, Costco now sells prime meats at a good price. You can also check out Tip Top Meats in Carlsbad (off Palomar Road, oddly enough around the corner from Costco).

It sounds like you ate at teh Ringside in portland.
