Johnny Rockets can be found all over the world, so I don't suppose it's new to most people. If it is new to you, you will seat yourself at a table or the bar in the fifties style diner. In some of these places you get singing waitstaff, but not in San Jose. Instead, you get nickel jukeboxes that hardly operate.
Try a malt, slice of pie, the fries are great and the burgers are delicious. They also have a dangerous chili bowl that is good for those with iron guts.
Johnny Rockets is around the corner from movie theatres and the park is a block away.
There is also a location in Campbell, in the Pruneyard Shopping Center.
