Want to make a dish a little more opulent, a little more expensive? Put a gold leaf on it. Whether it's uber-romantic desserts, overpriced martinis or flashy decor, gold leaf can be found lurking at several Washington restaurants. Since gold leaf basically tastes like nothing, it's flash that these places are adding with the ingredient. The sluggish economy has led to the retirement of some gold leaf accented dishes (R.I.P, BLT Steak's Burger for the 1%) but others live on.
