Regarding the dishwashers and non-kosher food being sold: I believe it’s a machlokes between the cRc and the OU as to whether it’s permissible to eat/drink in such a place or not. I was at a shiur a few years ago on it. I believe the cRc holds it’s not allowed, and the OU holds it’s fine. I guess it would depend on where you live, as the kashrus agencies are sort of territorial: if in the NY area, go by the OU, if in the Midwest, go by the cRc.
