Last night I was at Denny's, so I tried Smaug's Fire Burger. It tasted pretty good and was actually spicy.
But the desolation hit this morning. I wouldn't recommend this one, even if you like unhealthy but delicious food like I do. The burger is supposed to have spices in it, there's a spicy sauce, and deep fried jalapeno slices. Even if it's not too spicy for the tongue, it still might be for the stomach.
ETA: Also had the pumpkin pie milkshake and it was really good.
