Vitamins, prophylactics, Ladies products , shoes/sandals like Dr.Scholls and even cosmetics can all be obtained from most pharmacies. There are at least two decent organic-health food stores in Downtown Athens.
There is an agency that certifies the organic nature of these claims called BIO ELLAS. I don't know who certifies them...
These days, for better or for worse, there are a variety of other types of Greek restaurants, some mediocre, some poor, and some excellent. See the Athens Restaurant Guide for some I have dined in and some I lifted from The Athinoroma List of the Best Restaurants in Greece which in Greek. My favorite is the Yellow Bicycle or Kitrino Podhilato in GAZI. Its priced moderately by big city USA standards. There are one or two good ones in the Exarhia area too like wishbone on Valtitsiou Street right next to the Riviera open air Cinema. Its not a budget place but has a wonderful outdoor garden and micro-brewery beer from Crete as well as bottled Greek wine and house wine.
No discussion of Greek food can be complete with out the street vendors. They sell a variety of things. The best of which are nuts grown in Greece. Hot corn on the cob, bread, donuts, chestnuts and sweets are also to be seen on Athens streets. Coolouria are circular, sesame encrusted bread sticks and not particularly nutritious, but just the thing for a quick snack on the hoof, these round bread sticks, which look like bracelets, are inexpensive (about .70 euro cents) and readily available to busy Athenians on many downtown corners. You have to try them at least once! They traditionally have sesame seeds on them but sugared ones are sold too. The nut vendor should also be patronized and treated with respect as the nuts are fresh and well worth the price. They can be purchased for less and in bulk for taking back home
