I bought one for $2.99.
The sandwich actually felt a lot like a grilled cheese with egg and ham thrown in. The two slices were thoroughly melted, with the Swiss looking almost like mayo. They provided a nice, creamy, cheesy factor.
The sourdough didn't offer much in the sour department, but was toasted well on the outer surface and had a slight bit of chew.
