Have you ever taken the kids to see Discovery Times Square? If not, it's about time! This cool discovery museum offers a large-scale exhibition center that features cool rotating exhibits like "Body Worlds" (not for the faint of heart!) and "Vikings Exhibition" (where you'll have the chance to see more than 500 artifacts from the 8th to 11th centuries).
Be sure to check out all the other amazing museums for children (and to do it on a full belly from one of our 50 favorite family restaurants). Have little sweet tooths in tow? There just so happens to be a DC Cupcakes Cafe located on the lower level (open from 11am–7pm).
