Is there live music every night?

They have 5 shows a night, rotating performers. Shows at 5, 6, 8, 9 and 10pm. Lineup outside about 45-60 minutes prior to show.

Yes, there is live music every night. They do multiple shows each night too but definitely check the schedule. If there's a particular guest that you want to see perform either reserve a seat or get there early. There's almost always a line.

Yep, and you can stop next door at O'Brians to get a beverage while you wait in line.

Yes, 3 to 5 shows every night. Usually 5, 6, 9, 10...you will want to get there minimum an hour before for tickets. Rotating performers. The day I visited they had canceled the 5 and 10 shows.

Yes

Check the schedule. I'm sure they do.
