Arte Mexicano Nopal
The gentleman that owns this shop has stuffed it full of quality hand-crafted items, mostly from Oaxaca. The shelves overflow with distinctive black ceramics, hand-carved masks, copperware, plus other items. Browsing makes time go very quickly indeed, and you must go several times around the store as it seems every time you turn around, there's a new item that you missed. If you're in the mood for wood carvings, it seems he has a huge selection, from rustic containers, to masks. There's also a large selection of cooking spoons made from the Cuachalatate tree that he swears will last 20 years.
