restaurant recommendations near Disney concert hall?
If you are attending a matinee performance, you have more options than you will for a night performance.
Very limited options, and while Patina is very good, very expensive, etal., you may want to find a place that provides a shuttle service to the hall, which occurs mostly for evening performances.
Other than Sundays, the Colburn School diagonally across the street from Disney Hall has a decent café, nothing overly special but will suffice.
On the other hand, if you want to eat after a matinee performance, I like Taix on Sunset @ Alvarado. Nothing gourmet you understand, but solid nevertheless. Two wine lists, meaning you must ask for the better version. But the wines are quite good, very reasonably priced, and a surprising value.
