Santana Row or Lincoln in Willow Glen would be the analog to University Ave. Both are pretty nice to hang out in.
Campbell also has a nice downtown; while it's not San Jose, it's surrounded by San Jose and is basically the same metro and is VTA-accessible. There's also Saratoga and Los Gatos, but those are further out.
Downtown, I'll grant you, though. San Pedro Square can be OK, and the area nearer the University has some quirky stuff, but it has a ways to go. It's gotten somewhat better over the years, though, and I think BART coming to the area may accelerate that a bit since it can actually be a destination.
