Unless, the only Chinese food you eat is not completely authentic, is fried (like Spring Rolls and Chicken Balls, which aren't authentic Chinese Food anyways), is spicy (like Shezuan), has Mercury (like Shark Fin's soup), etc... use the caution for everything you eat.
The Hollywood Bowl concert season usually runs from June into late September or early October. Most events at the Bowl are produced in house, but there are also Lease Events, which have different arrangements for parking and different rules for picnicking.
Ticket information for The Simpsons Take the Bowl will be available over on the Hollywood Bowl's website. The big show will begin at 8 p.m. on September 12th and 13th, but will start at 7:30 p.m. on the 14th.
