8.5 to 9/10 - that is a good score for a Wurst Garb. Good meal for the money besides the taste?
Well, when it comes to food, it's the taste that sells it.
Not only were the wursts good, but their fries cooked in duck fat were also really good. It is quite pricey (i.e. my double currywurst and duck fat fries came to $20 with tip), but at least you get what you pay for, and you won't find another currywurst in the city, as far as I know. They have some cool beers on tap, but even there you will pay $8-9 for a pint.
On the other end of the scale, I went yesterday to the diner across the street from me, where a full breakfast was $6, and the beer was $2.83 a pint.
