Hello, while toting my camera around I need to get really quickly from
Piccadilly [by the Royal Academy] to Leicester Sq. Usually, I'd just
walk. But my day is jam-packed with meeting friends and then rushing off
for a matinée ("Madame De Sade", if you must know. I know, I know.)

Should I walk or tube (just one stop! And getting in and out of the
station might take as long as walking) or is there a perfect bus that
goes from Piccadilly to Leicester Sq/Charing Cross Rd? What would you
do? (Black Cab only in the greatest emergency.)

Thanks!
