Any Recs near Dorothy Chandler Pavilion?
You could walk down the street to Patina. I believe they're open until 11:00 on certain evenings with performances at the Disney Hall, and I'm almost certain they'll have a performance there on a Sunday night. Call Patina to check: 213.972.3331
I also love to go to the Bonaventure's revolving lounge. Great place for drinks and views of a lighted downtown LA.
