There's "art for days" at this "excellent" museum complex close to Downtown, which offers a "fantastic", "widely varied" collection "from all periods" plus many "must-see" traveling exhibits; insiders also suggest taking a "walk through the colorful and unusual tunnel" between the buildings or going for a stroll through the outdoor Cullen Sculpture Garden, home to more than 20 pieces from the 19th and 20th centuries; N.B. free admission on Thursdays.
