In response to this, in 1885 Nagreen decided to flatten the hamburger steak and insert it between two slices of bread, so that the public could move freely from booth to booth while eating his sandwich, an innovation that was well received by his customers.
Kao odgovor na ovo, 1885. godine Nagrin je odlučio da izravna hamburger odrezak i ubaci ga između dve kriške hleba — tako da kupci mogu da hodaju slobodno od šatre do šatre jedući kupljeni sendvič, što je bila uspešna inovacija.
