Downtown is a bit cheaper but the traffic and parking are terrible.
To me, South Point is the best! Its like old las vegas, lots if buffets, and I took my Daughter to dinner in the Prime Rib room, very elegant and dinner for about $25, and to top it off they had a special for $20 for a bottle pretty good red wine. It was less than $90 out the door.
My problem is its a LONG way from where I live
