Looking for traditional Mexican crafts and home wares, such as the beautifully colored, hand-painted bowls and plates you've eaten off of at so many restaurants? Head to La Ciudadela, an artists' market that for more than a century has drawn craftspeople from all over Mexico to sell their goods. In addition to kitchenware (handmade, blown glass swizzle sticks are a must-buy!), there are clothes, toys, and even musical instruments available for purchase. The market is big but not overwhelming, and bargaining is acceptable.
