Trader Joe’s has at last confirmed the second and third of the 3 stores that’ll constitute the idiosyncratic grocer’s Houston invasion.

And yes — the company is now ready to admit — one in the just-decimated hollows of the once-grand Alabama Theater, last known as the Alabama Bookstop bookstore (bottom photo above).
