I normally have a 45 minute limit in most museums, so the Hammer in Westwood usually suits me perfectly. And the café is a lovely option when I don't have my heart set on Persian food up on Westwood Blvd.
There really isn't a bad seat in the house at the Mark Taper Forum, and I love to see plays there as often as I can. The downtown restaurant scene is so dynamic that it's hard to choose - but I always end up at mine! Border Grill's limo shuttle service makes me feel special.
LACMA is situated in the heart of the city, set in a gorgeous park, and with the recent additions you can't beat it for an enjoyable afternoon. We usually top off the evening with a delicious sampling of Ethiopian dishes on Fairfax.
