Queso Fundido

Does anyone remember the Queso Fundido that Que Onda used to make? Served in a square cast iron dish with chorizo and onions. Crispy on the bottom, gooey on top. I stopped by to get some for lunch today and they don't make it anymore 😭.

Does anyone know a place that does it like this or at least very similar? Not looking for liquid cheese that drips off your chip before you can get a bite.
