And ofcourse you have hotel raddission and Soaltee as well as Hyatt !!  Yak and yeti , and annapurna too :D there are loads of hotels where you can have your reception at , depending on how cost efficient you want to be. 

New banquets with the parking undeground are not expensive as compared to the ones mentioned above :) 

i would suggest you go and visit Radission hotel, i know it sounds expensive, for its a 4 star i believe, but it is pretty much affordable if you are willing to spend a bit more :)
