Black-truffle-stuffed tubes of foie gras, $58 bottles of aged balsamic vinegar, tiny round tins of salty black fish eggs -- these are pleasant things to consider, especially if you're sitting at a marble counter, nibbling a delicious smoked-salmon-and-cream-cheese sandwich and contemplating the department stores around you as they employ entirely new adjectives to describe pants. This is something you should do if you find yourself caught in mall land, feeling a bit light-headed and susceptible to the marketing onslaught. Find the Caviar & More kiosk. Order one of the array of small sandwiches served on French rolls, such as the aforementioned salmon for $2.29, a cheese manchego for $1.92, or even the foie gras sandwich for $12. There is also a caviar menu, with one- or two-ounce portions served with toast points, maybe a little crème fraîche. The caviar runs from a modest $6.50 an ounce for salmon roe to top-of-the-line Beluga (here the Huso Huso, a "smooth and pearly" Russian caviar that costs $71 an ounce if you eat it at the counter).
