Well, an hour will cover a whole lotta ground from Pasadena, California!

So, you might need to be a little more selective when it comes to the sort of things y'all would like to do.
Oh, and, after y'all visit Griffith Observatory (should you choose to do so), you can head down to Vermont Avenue. There are plenty of great restaurants along Vermont just south of Los Feliz Boulevard.
Have you considered taking them downtown? You could visit Olvera Street or Japantown ...
And, come to think of it, there are some pretty great places to get a drink and/or a meal in Pasadena and even over in South Pasadena, California.
