I do not have reserved seating for a sold out show, but I do want to have dinner there. Is this possible?

Maybe. You might have stand up to eat. But you can still see the show

Go early and eat at the bar

I got to a show early and ate at the bar. They have tv screens all around as well so you can see it that way.

Get there early..the tables fill quickly and I think if you don't have tickets u may need to leave before the show

Yes it's possible.

We did, on the bar side at the few tables there. The downside is, you won't be able to see the show very well/at all if it starts, and may have to wait to be seated.

No
