Gold Coast is underappreciated, in my opinion. It's located right across the street from the Rio (and very nearby to the Palms), and has a huge casino floor for slots and table games. It's always packed with the old-timers, and maybe it doesn't have that douchebag flash that other strip casinos have, but it's a decent place to gamble and eat. Lots of restaurants (chain and original), room to play, and themed nights.
