The decor at the Uptown location is Chicago-urban-blues, complete with fake 'L' train pillars and blues bands on stage. While some of the suburban locations I've been to (like the Roseville 'fishing shack') have self-service with a walk-up counter, the larger Uptown store has table service and a bar.
Menus etc. can be found at www.famousdaves.com.
