I had one (curry wurst) when I was there a couple years ago. It was delicious! And they had squirt bottles of mayo out on the counter for those like me who use that on their french fries instead of ketchup (yech). I can take ketchup mixed in with something else that changes its flavor but don't like it just out of the bottle as a condiment.
Un-refrigerated mayo, Ms. Mod? For shame!!!
