Las Vegas 2020 Reception Help

Hi y'all, I'm planning my wedding from Texas and have booked my ceremony at Caesar's Palace Juno Garden on June 11, 2020. I am looking for suggestions for private dining reception still! Yikes, I know, I should have already booked that but after countless hours of research and email's I can’t decide on the right package. Does anyone know of a restaurant that will provide an open bar for 4 hours, and a family style dinner for 50 people for less than $5,000? Or is that not being realistic? HELP PLEASE!
