How about this as a pitch for a blues club? The best national blues acts every weekend, eight o’clock shows, free parking, and an all-you-can-eat Chinese buffet. What began 34 years ago under the name of Chan’s Egg Rolls and Jazz has evolved into the home of great blues every week. Visually, Chan’s is a blues anomaly. Instead of Southern folk art on the walls of a faux juke joint or blues memorabilia scattered throughout a dimly lit saloon, Japanese paper lanterns hang from the ceiling, tiny Christmas lights twinkle above the stage, and Chinese artwork adorns the walls inside John Chan’s personal blues parlor, a 125-seat banquet room. Throughout the years, more than a thousand blues performers have played here. In 2010 alone, 138 performers took the stage. Because Chan’s has a reputation as the blues place to be, you might be sitting next to Jerry Portnoy or Doug James or Duke Robillard, who, on an off night, has come to see a friend.
