I had my sister's wedding reception last year at New Baneshwor Banquet at Baneshwor height. It was really well organised.
The party palace in itself is quite big with plenty of parking place for cars and motorbikes. The toilets are quite clean and they clean them regularly throughtout the reception which makes it a pleasant experience. Food was also very good. And staffs and waiters are quite professional. Lastly, it is located at the heart of Baneshwor height, no if your party is in the evening, they won't be a shortage of public transporation. Plenty of taxis waiting for clients right outside of the party palace. Overall I had a very good experience with them.
