Boar's Head?
This Ralph's is awesome because it is insanely close to my apartment. As for its objective qualities however, it's always super clean and the deli ladies are very very nice.
Also, it has underground parking, unlike the one on University. Thank the powers that be too, because parking down in the Gaslamp is a nightmare. One of the coolest things I have ever seen is the escalator thingy/inclined moving sidewalk that takes you from the garage to the store. Totally cool. And don't worry if you need to get your shopping cart to your car--they have locking wheels on the carts once they are inclined enough, as well as an elevator.
They have a killer deli section too. The ladies behind the counter are really nice about giving you samples of the deli meat before you decide if you want to buy some, and the Boar's Head stuff always has one of the varieties on sale. YUMMY. And their sale prices are actually good.
Also, in drinking land, check out their wine aisle. I usually prefer Trader Joe's for such things but they actually have legit sales on stuff now and again.
