The venues are highly regarded, but many top name acts are booked to play the casino floor itself from time to time. It's considered to be a much nicer place to see a show than Foxwoods, and the Mohegan operation tends to book the acts on the quality of the acts rather than on the acts' history of bringing in gamblers [as is common practice at most other casino operations (including Foxwoods).]
