Sam's is a lot of fun to browse, but if you want to talk with their knowledgeable staff you have to avoid peak hours like Fridays at 5:00. Chicagoans should also check out Knightsbridge in Northbrook. Sometimes pricey, but every wine is there because he wants it to be. Definitely a Burgundy fanatic, but also tons of Bordeaux, Italian, and others. Still carries quite a few 1997 California Cabs, for example. Try finding those at Sam's or Binny's.
