San francisco has great restaurants, but I'm a Russian Hill guy. I don't tend to roam far for food. Fortunately, Polk street has everything I need. Sure there's Mexican, Chinese, and Thai, but there's also Andrew and Co. Side by Side Gourmet which specializes in Carry Out Prepared meals.
Pros: Excellent Selection, Fresh Food, Nice Staff
Cons: Parking on Polk is a lesson in patience.
