Looking for a BIG restaurant in westwood

Hi I need to find a place for a group of Australians about 60 people. We want to come in and eat off of the menu, and separate checks for parties of four or more. I'm worried about inundating a place that's too small. Meaning the wait staff and kitchen can't handle that amount of orders all at once, and the seating. Is there a big place, moderately priced? I'm visiting from Tampa, and because I'm the yank, it's been put to me to find a place. Please send me your recommendations, I can do the contacting of the restaurants. Many thanks!
