Going to WDCH for a show tomorrow night (Sunday). Do you have any advice on where to park and where to get a bite, in the immediate area of the WDCH? When to get there? Showtime is 7:30PM.

There's self parking in the garage under the concert hall, details here

The cafeteria inside the concert hall isn't bad.

One option is to arrive early and have dinner at Cuidad, south of WDCH. Sunday is their tapas night and the food is great. They also have a free shuttle that goes back and forth from WDCH, so you can just park in their garage for the night. We did this a couple of weekends ago and it was easy and pretty cheap (total parking bill = $5).

Patina is right in the WDCH, so that's the closest and easiest option. There's also a snack place inside if you don't want to sit down and have a full dinner.

The Pantina restaurant inside WDCH is supposed to be very good.

Little Tokyo isn't too far from WDCH, but probably too far to walk.

Patina = $$$$ and 2 hours.
