Restaurant at the Griffith Park Observatory
I just ate there on Saturday. I had the rare roast beef sandwich (which wasn't rare at all). All it had on it was the roast beef and a slice of cheddar cheese, no greens or anything. And it came with a container of whole grain mustard- more mustard than you could eat on 5 sandwiches. Others in my party had the ham and cheese sandwich, the cesar wrap, the strawberry parfait, and a muffin. Nothing was that great. I think I'd try a salad next time, they looked better. The bread was good though. Everything was expensive. $2.50 for a 20 oz coke sandwiches were $7-8. We ate at 1 PM and there was no line; it was very crowded at 11:30 though.
I initially wanted to bring a picnic lunch too. Their website clearly says no picnics and no food on the shuttle. My mom walked on with a drink in her hand. When we got to the top there were a couple picnic tables with people eating full spreads of Subway and other lunch items. Why picnic tables if there's no picnics? But there are also ash trays on the top of some of the trash cans and they also say there's no smoking in Griffith Park.
The observatory itself if fabulous. I highly recommend the planetarium show.
