The French country inspired boutique at 3927 24th Street is closing up shop and moving. (Even if you don't shop there, you'll remember it as the store with the twittering birds sounds as you walk by.) A woman behind the register confirmed the store is "probably" moving to Palo Alto - and the retailer needs to be out of the building by the end of the month. Much of the inventory is already gone, and what's left (lots of Christmas stuff) is selling at a 20-40% discount. Unclear what precipitated the move but it feels sudden - and the store's Web site theurbannestsf.com is currently offline.
