Read this thread yesterday, and couldn't wait to try it.
My wife had a stressful day at work, and hamburger/fries is a favorite comfort meal, so I suggested it.
We each ordered the regular burger, one with fries, the other with sweet potato fries. The burgers had a great grilled flavor,
and were sloppy fun to eat. Definitely very pink in the middle, which I like, but can understand why people may be put off.
Fries were great too - crispy outside, soft inside, good potato flavor. Also liked the chocolate milk shake.
The only negative was that he music was very loud.
