Man, Daawgon would have you think the San Jose area is a ghetto instead of being in the middle of the Silicon Valley.
Here's some great places to visit while in San Jose for a nice "restaurant on the street" experience.
(1) Consuelo Mexican Bistro in Santana Row--best Mexican restaurant in the Bay area besides Guaymas in Tiberon (Guaymas you can only get to if you take the Blue and Gold Ferry line from downtown San Francisco--and it's right where you get off). But back to Consuelo's. Santana Row is the very "high end" shopping district in the Silicon Valley and is just a short taxi ride from either downtown or the airport (think of these three as forming a small triangle). This area is also across the street from the largest regular shopping mall (Westfair) in the area also,and right across the street from the Winchester Mystery House which is the #1 tourist attraction in the vicinity.
Visiting Santana Row will show you a bit what Beverly Hills' Rodeo drive is like if you haven't been there yet. Most of Consuelo's stuff is reasonably priced--although their tequilas are all over the map--from $1 a shot to $500 a shot for the best tequila you can buy in the world (and which they only sell 500 shots of per year--and Consuelo buys 50 of these shots per year!)
(2) South of Santana Row another 10 miles of so (before you cross the mountains over to Santa Cruz and Monterey) is the small upscale town of Los Gatos. The celebrities of the Bay area either live near here or just north of Palo Alto. Among some of the better known celebrities who live here would be Peggy Fleming, the olympic skater (who has lived here for over 30 years), Neil Young (the rock star), Tom Selick (the actor), and south of here in the mountain city of Scotts Valley (my home town) used to live Alfred Hitchcock, Clark Gable and Jean Harlow, and Humphrey Bogart. Anyway, the city has only two main streets (Santa Cruz Avenue and University Avenue), yet it has five major restaurants (California Cafe, Wine Cellar, Steamers, Kuleto's,and Manresa, which won a James Beard award for being one of the top 40 restaurants in the US)--and it also has numerous small shops and bars along its 12 blocks or so and a small park where people love to browse. P.S. Brazil stationed their soccer team here back in 1994, when they won the World Cup FIFA Soccer tournament, which was held in the US for the first and only time. Obviously, the Brazilians partied every night they won (and most nights in-between)
(3) If you want great pizza, right downtown in San Jose is Amici's (famous for their east-coast NY-style pizza). It's great, and walking distance from the HP Pavilion. I often go there for pizza just prior to going to San Jose Sharks games at the HP Pavilion during the winter months. (There is also an Amici's across the street from the baseball ballpark in San Francisco--which is where the Caltrain ends if you stay on it all the way from San Jose to San Francisco).
(4) If you like Thai food, there are two Krung Thai's just blocks from Santana Row--both on Winchester Boulevard--one just south of the freeway (the closest one, but also the old one)--and then about 3 blocks north--which is the new one. Amazing that these could be so close to each other--but they are both usually completely full all the time during the dining hours--which tells you that the food is good.
