Olive oil, cheese, tea, wine, and chocolate. When I travel, I often find tiny shops centered around these delicious things, and I rarely get tired of the stories behind them (though I hate the uninspired trend of "pour your own olive oil" shops). In London, we visited tiny Prestat chocolate shop, a Royal Warrant holder, located in the Prince's Arcade off Piccadilly. How did I live this long without tasting one of their caramel and sea salt wafers? Pick up a box of half the wafers robed in dark chocolate, half robed in milk, all with smooth caramel and just a hint of sea salt. The whimsical, bright boxes make it a great gift to lug home.
