My home bar changed its name from "Rookies" to "Chicago Sams" in February or March of last year, well over a year ago. When we do well enough to make the "national" leader board, the site still appears as "Rookies", most recently just this past Thursday. (On the BT website - when it's up - the place name is displayed correctly.)
Which is okay with me, as I still think of the place as being "Rookies"; the name of the place is really the only thing that has changed.
So Botanist's site may appear as "Diamond Lil's" for quite some time, based on my own experience.
I hope the grand opening goes well.
