Strictly Personal Opinion:
(Applies to sports betting only...not poker or pit games)....
BEST ODDS: MGM GRAND (while other books employ sports/odds experts, MGM is somewhat behind the times and often has soft lines -- or is slow to react to Don Best movements). They have a management style that they would rather not employ any wiseguys, so they take a few hits, and just make it up on volume. In terms of everything else, I despise this casino. This is everything a casino should not be (corporate-oriented, impersonal, and it takes 15 minutes to find a place to get a cup of coffee). MGM is the anti-Christ.
BEST VISUALS/SERVICE: (tie) MANDALAY BAY and MIRAGE Both books are first class in every way. I give the edge to MANDALAY, because it's usually not as crowded. If you get bored, you can always go over the the House of Blues, 40 steps away. Furthermore, it's one of the first casinos to be built since sportsbetting has effectively taken over horseracing as the premier wagering/spectator sport interest. The seating reflects that, whereas some of the oputdated places stil have 3 horseplayer seats for every one sports betting seat. The big screen TV at MANDALAY is awesome. I love this casino.
BEST PLACE TO GET TO KNOW A FRIEND: I like the LAS VEGAS CLUB downtown. Lot's of small time bettors on benches eating hot dogs. It's the "old Vegas." The entire casino has a sports theme. No high rollers here, but probably my favorite hangout when watching sports (note: TVs are small and it's really small time...but you can't beat $1 Heinekens)
SIDE NOTE: You mentioned BINIONS HORSESHOE. The World Series of Poker is starting this weekend. That place is going to be a madhouse. Forget about watching a game in there. The sportsbook is terrible. Of course, I've probably put more money through the windos at Binions than any other joint.
OTHER COMMENTS: STARDUST is a great place for the ultra-serious sports gambler, but the place hasn't had a face lift since the 70's. The place is also a freakshow at times. You see all types in there. LV HILTON used to be one of my favorite places, because it is seperate from the casino and you can drive up and be out of your car and in the book in 30 seconds (STARDUST has this advantage too). SAHARA is just as bad as the downtown books (small TVs, tiny book). I have no opinion about BALLYS, since I haven't been in there in ten years. CAEASARS is CAESARS, but gets more of a tourist crowd. I've actually seen viwers in there watching games and they didn't have any action (horrors! -- kick their asses out of the seats!). I like the RIO, which is cozy, but on weekends you can't get a seat. Also, there ar enot enough TVs in the RIO, considring its a new casino and large enough to handle an expansion. I would not set foot inside NEW YORK/NEW YORK if they were giving away free lobster. It's not a casino, it's a Disney Park.
