A lot of tourist shops in Kalambaka (most of which close for the winter) sell the usual carved wooden canes and spoons, rugs, ceramics, and more rugs. One shop worth a look: Kava Nikos, on the main drag, 114 Trikalon (tel./fax 24320/77-881). This small liquor shop carries a good selection of wines both in the bottle and from the barrel, and also stocks local Macedonian and Thessalian tsipouro, a firewater that makes ouzo seem like a delicate aperitif. If you're lucky enough to be in Kalambaka on a Friday, you can join the crowd at the farmers' market that spills onto the streets off Kondyli. Many of the monasteries have small gift shops with religious items.
