Since there was some discussion of this in recent weeks, I decided to take one for the team...
The "Spuderito" is a burrito consisting of french fries, lots of cheddar cheese, hot sauce and possibly a touch of sour cream.
I suppose this dish may have some value to a frat house vegetarian on a bender, but basically it's not even worthy as a novelty. At least they didn't try to throw pinto beans in too.
Their Coca-Cola, however, was excellent.
