a serious dairy pizza shop with all kinds of cheese & other dairy stuff & the right near it serious meats & steaks etc… with just a thin movable wall to separate it, do you call that kosher? i don’t know any hechshar that would approve it unless they are corrupt-as many are R”L as long as you pay them for their approval paper but never or hardly ever come to check on your restaurant/ bakery-
IACISRMMA:MY kitchen has separate sinks & ovens with the sinks being the separator between meat & dairy counters…. my home also is not a serious business operation & is easy to remember what & where is what when it comes to meat & dairy versus a serious restaurant business.
on a separate note i have done Hashgacha in Pesach hotels for many years working side by side with many other mashgichim AND BOY HAVE I CAUGHT so many serious kashrus issues-after hotel was kashered of course-that other mashgichim just sit & don’t realize what a serious issue it is….
regarding bakeries: ALL have separate ovens for dairy danishes & SOME even have a complete separate ROOM for dairy ovens for baking. do your research….
