I have no clue how I ended up a fan of MGM restaurants on Facebook. However, I came across a great deal while browsing there.
Buy one entree get a second entree free at:
Diego
Craftsteak (Great bargain, I think)
Nobhill Tavern
Pearl
Seablue
Fiamma
and some others....
The link I have is :

Hope someone can use it!
