Santana Row is a mostly upscale shopping complex with hotel and luxury housing attached. On a nice evening, there are pleasant outdoor eating options and it generally was designed to have more of a walkable area than most complexes of this type.

But it's really not much like an authentic town center in the types of amenities it has and, while you can walk to a number of restaurants, I expect you'd still have to end up driving for most things. The area as a whole is not very walkable and there are limited transit options.
