I use three 4x6' tables that go together with bolts (that I built myself). I can arrange them in several different ways as hte side panels come off. I generally use with the 6x8' setup (bottom picture) or the 6x12' setup (middle picture). I can break the whole lot down and store it when I need the whole bar for family gatherings or holidays.
The bar is officially called The Feisty Wench and I'm particularily proud of the logo (see below).
I have a game of Muskets and Tomahawks this evening that I'm really looking forward to (batrep to follow).
