The badatz and landau have very strict rules to their hashgachos, just just the kashrus aspect of it. The badatz yerushalayim wont give a hechsher on SPRING drink because it has a picture of a man surfing on it. It is their choice to decide who gets the hashgacha and they will only certify things that they themselves will be confortable having in their own home. Resteraunts cannot be open late. That is why many resteraunts in Geula prefer NOT to have the badatz and to be open later. You want badatz, you close earlier.
When the Mir opened in Bais Yisroel and until recently (10 – 15 years ago) there were NO resteraunts in the area. The yeshiva was at the end of an industrial area and the closest “hang outs” were further away. Now, stores selling all sorts of things, opened within daled amos of the Yeshiva. And the Rosh Yeshiva as well as the mashgiach, HaGaon Aaron Chodosh are taking action.
And BTW, smoking is banned in all of the Yeshiva buildings and dorms. Noone smokes in Yeshiva. Maybe they smoke in the stores around, but in Yeshiva, NEVER!!
