So it has to say halal on the package the special kind of gummies only correct ?

If a restaurant advertises halal and you ask them if their whole menu is halal and they say yes there is nothing more for you to worry about this point correct you just go based off what they say correct ?

1- Writing "Halal" does not mean any thing, if it is imported from Non-Muslim country, if it is of animal base.

2- Yes, if the seller is Muslim.
