The Lion's Tap is one of our favorites as well. We were just there this past summer, engaging in a hamburger orgy with fellow Roadfooder Davydd and his wife, Nancy. These are pictures Davydd posted on the Roadhouse Bar-B-Que Sauce Summer Tour, 2008 thread.

In addition to visiting The Lion's Tap, we also completed the Jucy Lucy circuit, finally visiting the 5-8 Club. Previously we had been to Matt's and The Nook. While I am reluctant to declare any one of these "The Best", from a strictly objective viewpoint, I think Dad and I were agreed that both The Nook and 5-8 Club served a better quality burger than Matt's. Each place offers its own charms, and it really doesn't matter which one originated the Jucy Lucy, they are all worth visiting at least once.
Oddly enough, The Lion's Tap does not serve a version of the Jucy Lucy.
Thanks for sharing your Roadfood memories, hope these photos brought a smile to your face.
