How Long is the Show?

My husband and I are going to a Kurtis show in a few weeks (yay). Just wondering if you've been to the show, typically how long does it last?

Normally I wouldn't care, but, this is our first night EVER without our 8 month baby and wanted to make a date night out of it as we never get this opportunity. I wanted to book a nice dinner but just not sure when I should make the res for as I have no clue when it should end.

The tickets say show starts at 6.15pm.
