The poker room at the Horseshoe is in a large area at the back of the old Mint side of the place. It looks like it probably used to be filled with slot machines that were cleared out for the poker tables. It's fairly quiet since it's set apart from the main casino, but it lacks any real atmosphere. The floor had a lot of tables, but it didn't feel cramped.
In the 2/4 game that I played in, the competition was average. There were some decent players at the table, but just as many calling stations. Overall, the competition was tougher than at other places, but not as hard as I would have expected. The situation in higher limit tables may be different but I didn't play those so I can't compare.
The dealers knew what they were doing but didn't seem terribly friendly. They were just quietly doing their job, which is usually fine by me.
I didn't see many cocktail waitresses come around. Drink service seemed pretty spotty.
Management seemed fine, they got me a seat quickly and that was about it. They were running a tournament when I played, and had the current limits and time at each level prominently displayed on large-screen TVs.
A guy playing at my table had hit a royal earlier that day and didn't get a jackpot bonus, so I think it's safe to say they don't have any jackpots. I didn't ask for a comp so I'm not sure what (if anything) I could have gotten.
