A member suggested a meetup at Zinburger, located near Southpoint Mall in Durham. It's a small chain (10 locations on the east coast) located out of NJ. They specialize in burgers and cocktails. Their burgers look HUGE and they also have a shake menu that looks pretty incredible.
Here's a link to their menu: http://zinburgereast.com/assets/zinburger-menu-durham-1213.pdf
