its the landmark of the country & famous worldwide for gambling. when any person hears the name of the city the first thing in their mind is gambling. such a place yidden should not go to or live in
if a certain museum had an avoda zara in it but not to us just to a different religion but to us it was just a stone, we still wouldnt be allowed to go cause it wouyld be like supporting the avoda zara for every person that passed by in the museum & saw us looking at it. its basically like walking into a church or mosk although the person will just stand there & will not pray it is ALWAYS forbidden to walk into it
