Bread

I'd like to know the difference between a Portuguese roll in a Kaiser roll and when I said Portuguese roll I mean the hotter darker thicker type bread compared to the white lighter Kaiser roll type read in a town in in in a town called Hoboken New Jersey there is a bakery called Dominick's bakery they have the greatest bread you'll ever taste in the world but they don't make like Kaiser  type rolls than a soft and light they make like thicker darker heavier roles that are just fantastic I think it's it's like a Portuguese roll but they also make them long and a Portuguese rolls. is small but I would just like to know that kind of bread that that's called.
