Several of these items I’ve had and didn’t care for. Primarily, I’m thinking of Heart Attack Grill and the Quadruple Bypass Burger, which tasted as if they had soaked it in hot grease from the fry cooker. Seriously, that was one greasy, nasty, burger.
On the other hand, many of these I’ve enjoyed (Olneyville New York System Weiners, for example).
And these are pretty much fast food. Most of the seriously over-the-top unhealthy food I’ve had came from fancy restaurants (like the fois gras poutine at Pied du Cochon in Montreal…)
