I used Mapquest to plot a route from the Flamingo to Terrible's .... it's approximately 1.25 miles .... walking south on Las Vegas Blvd to Flamingo Rd then east on Flamingo Rd to Terrible's which is at the corner of Flamingo Rd and Paradise Rd. That's the easiest way (if you're not fully familar with the area).
However, you might want to get a free map from Mapquest as there is a shortcut which could save approximately .25 mile by exiting the back of the Flamingo hotel east to Audrie then south to Flamingo Rd then east to Paradise and Terrible's).
