Los Angeles' Greek Theatre opened in Griffith Park in 1931 as a condition of the land grant that made the park possible. While originally it had many Greek design features, this back facade is all that remains.
The Greek Theatre seats about 6,000, making it a relatively small venue. These seats were in the front of the back section, to give you an idea.
Food and drinks are available for purchase, but at outrageous prices. You are better off bringing your own food and eating at picnic tables outside. Of course, if you eat at the Greek, you'll get these nicer sitting areas.
Being a smaller venue, the Greek Theatre hosts smaller acts. I saw Barenaked Ladies on my last visit.
