Okay, the line sucks, especially in the middle of winter. It's not as bad as it used to be, when people lined up for hours for a single cheese cake. But it still takes some getting used to, when other bakeries make all the stock in the morning, and then sell them until they're cleared out. Uncle Tetsu's approach of baking them continuously all day means that you get a still-warm cake right from the oven. And it's one of the lightest, fluffiest meringue-like cakes that you'll ever have (if you like that sort of thing).
The madelaines are fine, but nothing special. You know what you're really in line for ;)
