Situated nicely on the courtyard of Fisherman's Wharf, Cobb's features nightly lineups of talented comedians. Both tourists and locals are found here, laughing themselves to tears. Wednesday's three-hour "All-Pro Showcase" has 14 comics, featuring well-known, occasionally famous, acts. Previous performers include Robin Williams, Jerry Seinfeld, Rob Schneider and Kathy Griffin. It can get expensive with a cover and a two-drink minimum, but can you really put a price on joy and laughter?
