Whatever they're whimsically calling "burgers" are disgusting. They're not meat patties, they're some kind of meat paste.
There's an aesthetic, a texture, and a taste that accompany a burger craving. When you order a burger, you're expecting a burger.
I have no idea how Gostana gets away with the trash they serve that masquerades as a "burger", but if you actually *like* hamburgers, do yourself a favor and order a hot dog.
