I think my irrational attachment is the most irrational of all the ones mentioned so far, as it is an attachment to a restaurant that is no longer in business--Rupperts. Rupperts was one of the first nice restaurants Wife and I counted as one of "our" restaurants when we moved to DC. We weren't there often enough to be regulars, but we loved the place. It was somewhat out of the way, dark and jazzy, spare yet homey, with a thoughtful wine list and food with ingredients so delicious the trick was figuring out how to let them be, rather than cover them up, it seemed. Could a spoonful of cauliflower or a slice of buffalo, or a piece of brussel sprout (!), ever taste better? Oh, and don't let me forget the breads, and the spreads.
