I grew up in Chicago, and I must second this. The tour is amazing.<p>The U505 initially was outside the museum, but a few years ago they moved it into its own beautifully done concrete hall [1]. I <i>highly</i> recommend it if you&#x27;re in town and have the time.<p>[1] <a href="http:&#x2F;&#x2F;www.msichicago.org&#x2F;fileadmin&#x2F;Exhibits&#x2F;permanent&#x2F;u505&#x2F;exhibit&#x2F;U505_wide_608.jpg" rel="nofollow">http:&#x2F;&#x2F;www.msichicago.org&#x2F;fileadmin&#x2F;Exhibits&#x2F;permanent&#x2F;u505&#x2F;...</a>
