My favorite sports book is at the Bellagio. They have really nice leather chairs and the atmosphere is pretty relaxed. You also have a lot of big screen tvs to watch the games. Caesar's Palace is another great sports book. It is one of the biggest and most active in Vegas. Other sports books that I enjoy include Bally's and Mandalay Bay. One sports book I found to be funny was at the Luxor. It is very manual and the lines are handwritten on a white board.
