For $6, you can get a nice 6oz "homemade" burger. Add a few more quarters and you can get bacon or cheese with it. They have other burgers as well (classified as "char boiled") but those are 3oz apparently.
When the patty is ready, they'll ask you what kind of toppings you'd like in your burger, such as tomatoes, onions, pickles, lettuce, and some sauces.
I found the burger to be OK. Some found the meat to be a bit dry.
Definitely lots of grease coming from it.
