-Behind the Flamingo (off strip) an Italian Restaurant about a block away called "Batista's Hole in the Wall". Best Italian food you'll have in Vegas, extremely reasonably priced (like $15-$20), all you can drink wine. I go here EVERY trip.
-Mandalay Bay, House of Blues very good drinks, have some decent entertainment there.
-New York New York, the dualing piano bar in the middle of the casino (name?) and the Irish pub are good. The ESPN sport centre in there is good too if you want to watch an event.
-MGM Grand, Craftsteak for dinner. $100.00+ a plate but really good. Next to it is Emeril's restaurant which is about $60.00/plate for pretty darn good food.
-The Bellagio, they have a good Scotch&Cigar Bar in there...can't recall the name.
-(edit) Margaritaville seems to be popular with the ladies, but better(more booze) and cheaper and bigger Margarita's at Mandalay Bay in the House of Blues during Happy Hour (3pm-6pm I think...)
-Ceasars Palace the Forum, cool place to walk around and buy expensive stuff
-The Venetian, inside near the indoor river there is a small cafe that does a decent breakfast (and cheap!). A nice 'outdoor' indoor experience.
-Stratosphere for cheap gambling.
(I left it assuming you wouldn't care...)
-Sapphire (A), or Spearmint Rhino (A+) for strippers [girls]...no clue where you'd go to see dudes...

There's some delight in ale and wine,
And some in girls with ankles fine,
But my delight, yes, always mine,
Is to dance with Jak o' the Shadows.
