I need to find a restaurant in Westwood to take a group of approximately 8-9 undergrads and grad students. Type of food is not important, as long as its good. Would like to go somewhere with a festive or warm environment that is able to accomodate a group of this size (on a weeknight). Also, I need it be inexpensive, since I am a grad student myself and I am treating. Any suggestions for inexpensive, but yummy and festive options?
