What building has the really bright lights in st Louis by the gateway arch? -

Probably Lumiere Place Hotel and Casino...which is not too far from the Arch. It s along the Mississippi River and the whole thing is lit up in red and yellow and stuff.

lumiere place esp. with that big lit up billboard they have..... around the old courthouse all the lights underneath the arch that shine on it. i would say busch stadium, but it is a little further away from right by the arch.

Anheuser Busch
