I’ve had to do this a couple of times and Bistro Du Jour was a comfortable, pleasant place to sit and dine by myself.

Loads of choices, OP, depends on what you like to eat. The Wharf has a website which lists the options. Hope the kids have fun!

I'm taking my kids and her friends to the Megan Maroney concert next week at the Anthem at the Wharf. I don't have a ticket so I'll be waiting around for them by myself. Any recommendations where I can eat a nice meal and then chill somewhere while waiting for the concert to end? Should be over in less than 2 hrs.
