Depending on the size of your group there are some different choices right in that area: Munchkins, the restaurant in the Culver Hotel probably has the most room, they do have a full bar, and last time I was there they had a sort of asian fusion menu with decent food.
Bistro de la Hermitage is a small authentic French bistro very close to the Kirk Douglas Theater which has a great ambience but may not have the space. I think they serve only beer and wine also.
San Gennaro is an Italian place with mediocre food, a full bar and a sort of "desperate to be hip" vibe, but they can accomodate groups and the pizza is pretty good. Just don't expect anything spectacular in the way of food.
These are the three I can think of that serve alcohol of some kind and are in the vicinity of the movie theater. Ford's Filling Station may have just opened but it looks pretty small.
Ford's is set to open on Valentine's Day. It's not huge, but it's certainly not small either, and has two heated patios as well. It looks like a nice mix of updated meat and potatoes-type fare, ribs, pork chops, burgers, etc. with a few non-meaty selections too.
