Not excessively...
Do be prepared for the $20 cover (Though it's worth it), and the $15 Hendrick's & Tonic I drink (A $7 drink in Buffalo, and prolly Bingo), or $12 Guinness. Amazing show; amazing musician; worth the drive.
But, heck, it's Les-frickin-Paul. And it's a fairly small club. It would be about half the size of whatever they call the old Chuck-E-Cheeze country bar (I forget the name.)
If you're ever up in this neck of the woods, it's like seeing a show at the Tralf. Awesome location...
I wish I could have taken Pics.
