Within the Meat Market is H Ipeiros Restaurant where you can get a great meal for very cheap. Many of the workers eat here.
I eat here a lot. It is famous for its Patsa, a tripe soup and Pothi which is soup made from the foot of a cow. Both have beneficial properties
and working class Greeks eat them when they are feeling low as I do when I have a hangover. Does it help?
I don't know but I like the taste if not the texture. They have other stuff too and all on display and made fresh not only every day but all day long.
