Chassam Sofer Petach Tikvah is not something we rely on generally. Yes I know katzefet is that hescher and sometimes we’re lenient about that and products. But a general resteraunt with it we won’t go to.
People don’t eat Beit Yosef due to it being a sefardi hescher and the ashkeanizim discriminate against sefardim a lot and there’s a lot of politics. Most people I know eat bet Yosef, for pareve and milk due to differing minhagim for meat. We were told it’s fine for meat and chicken as well.
