Referring to a
restaurant, meaning that the restaurant is
kosher, but not overtly so. A "regular" restaurant that just happens to have a
kashered kitchen, and serve kosher food. That is, there's no
Hebrew writing on the
windows or on the
menu, but nonetheless the restaurant is
kosher. Still, you'll usually see a
netillas yodayim cup in the restroom.
Very different from kosher-style restaurants which do not serve kosher food, nor have kashered kitchens.
