Bottega Louie is close by, reasonably priced, and the food is good. It can be busy so I'd recommend having reservations for the inside restaurant part but if you want to just wing it, it's usually not that long of a wait to sit at the tables by the bar and the menu is the same. I like that it's an exciting "night out" kind of place and good for people watching.
It's walkable but probably not comfortably if you are dressed up and all. It's a 7 to 10 minute drive to the Disney Music Hall.
We are having our work holiday lunch in a few weeks and need to find a good restaurant for lunch in Burbank.
