Hey @lowqualityfacts , here's an idea for you:

"The Grand Union supermarket chain, once common through much of the Northeast US, has this name because the original location was at the corner of Grand Street and Union Avenue, Williamsburg, Brooklyn."

[Amusingly, the chain's corporate headquarters was in Brooklyn for a while, but it is not where it was founded nor in the right neighborhood for this low-quality fact to check out!]
