San Diego is different from San Francisco in that everything is not centralized in a few mile square radius. Such as there is only 1 good craft brewery downtown, the other 20 are in the suburbs 15-45 minutes away. But there are many buroughs that are unique to their own that you need to look a little deeper to find since their not right up against each other: Point Loma, Ocean Beach, Pacific Beach, Encinitas, La Jolla, North Park, Hillcrest, South Park, Miramar Rd. (Breweries), Balboa Park (Zoos, Museums), Coronado etc. In San Francisco they would all border each other, but not so in San Diego.
