Affordable places to throw a dinner to 10-12 people?

I'm the current head of a cultural group/unit at our college. And I'm about to leave the college in 3-4 months. So I pitched in the group that I would like to take them out one last time before I bid goodbye to the place. I'm looking for suggestions to host a dinner party to 10-12 people. I would wish my budget to be 5-6k overall; I'm not looking for ala-carte since that would make ordering difficult and all carte menu is expensive 😟 (Don't judge me, i don't earn as of now) However, my group is mostly gen z who's into all these aesthetic places and cafes; so I want to take them to a decent-ish place; which isn't very cheap. So looking for suggestions of a buffet place or something. TIA. And apologies if this question has been reposted. EDIT: It seems like there are not many options in my budget and requirements, so if you have other suggestions which don't strictly adhere to my requirements, please comment that as well. Also, please specify details of the place you're mentioning like: •Ala Carte/Buffet •Approx price per person •Quality of Food •Service Quality •Overall Ambience
