ISO Karaoke with Good Food
Backstage in Culver City (across from Sony) has fun karaoke on Thurs, Fri, and Sat. They have pretty good bar food items, especially the mac-n-cheese and garlic fries. I haven't had the wings, but they're a popular order there, as well. They also serve a selection of burgers, sandwiches, and salads. It gets pretty crowded, so it can be difficult to get a table unless you go a little earlier.

I did a party at Orchid in Koreatown. Cool private rooms and food was ok. The other place that looked like what you are searching for is La Defence, though I haven't been myself.
