I had no idea there was a hot link...sounds kinda icky to me.

I have to be honest and say that we don't really eat that much at DCA, so I didn't know they had a corndog castle or that it was links instead of dogs, but thanks for the warning.
We try to avoid eating at DCA because I feel the choices are just so-so and frankly- I'd rather be at DL. We have done Taste Pilots a couple times and it was ok. Not the worst, but not the best. In general we try to stay away from a burger when visiting because if I'm going to eat a burger while on vacay, it's gonna be at In-N-Out!
