Great deli and market! I'm all about the house special sandwich - the bread is warm and crispy, meat is good (boar's head) and nice variety of veggies on the sandwich, including sliced bell peppers and olives.
Z's also has a small selection of grocery items with candies, spices (including vegeta - sometimes tough to find) and assorted pickles/olives. They sell big jars of all sorts of pickled foods - I especially remember the green tomato pickles (what would that taste like?).
Overall, great little place to get a GREAT sandwich.
