Not everyone hates NBC's controversial coverage of the 2012 Olympics ... in fact, the network just got HIGH PRAISE from its rival ... CBS President Les Moonves.

Les and his wife -- "Big Brother" host Julie Chen -- were on a double date at Madeo in Hollywood with mega-movie producer Brian Grazer and his GF Keli Lee ... an ABC casting executive.

But as the 4some left the restaurant ... Les made it clear, he's a big fan of the way NBC is handling the Summer Games ... despite criticism from fans who are upset the network isn't airing some of the competitions live.
