A place for hosting small party

I am looking for a place to host a small party of around 50 people- close friends, family and relatives. Which restaurant, hotels will be a good option considering - I need good food especially non veg dishes. I am also thinking of getting some decor done either through the hotel or independently if they allow? If the place has dining halls and such that'd also be great. Has anyone tried the airbnbs in lucknow? Are they a good option? Affordable as well as highly priced options are welcome as long as there is no compromise on quality. Please include charges if y'all know. Really appreciate your help.
