Mirage has one of the better Sportsbooks on the strip with really good seating but plan on getting there early 2+ hours if you want a seat. Drink tickets were one per $100 bet. Across the street at the Venetian drink tickets took $250 bet. I hear the Superbook at the Westgate was renovated this past fall and was close to completion and is expected to be a fun place to watch the games.
Off the strip, I prefer Red Rock Resort. Great viewing, good seating and drink tickets were two per $100.
Another option is to place your bets and go somewhere else than the Sports book to watch. There's a new pedestrian mall next to the Linq (just look for the Ferris wheel) with a number of good bars for game watching. My favorite is the Yardhouse with 130 beers on tap.
