Let me preface this post by saying that both of my parents are North Carolinians, and I was fed lots of NC BBQ growing up. (Er, specifically Eastern NC Carolina BBQ.) So I went to Piggy Wiggy with some expectations.
I ordered one thing: the minced pork NC BBQ sandwich ($4.99), with a small side of coleslaw meant to go on top (25 cents extra). For anyone who doesn't know, this means the pork is simmered with a clear hot pepper vinegar sauce. The WaPo's reviewer said get the pulled pork (instead of minced) with the NC hot pepper sauce for "the best of both worlds," but minced is the traditional way. Besides, the woman at the register told me they just chop up the regular pulled pork to make the minced, so it's not like you're missing anything.
To sum up the sandwich: it was damn good. Not quite as good as what I've had in NC, but very close.
1) The serving was very generous. The meat spilled over and off my sandwich.
2) The meat was nice and hot, very moist, and had a great smoky flavor. It was tender, but not quite as tender as I'm used to.
3) There was NO cartilage or excess fat. This is somewhat unusual for NC-style BBQ. I missed the fat, I did not miss the cartilage!
4) The sauce was great with a real kick to it.
5) The coleslaw was only so-so. I like mine with more vinegar. But to me this BBQ requires coleslaw on top, so I'd get it anyway. (Or better yet, buy a pound of the stuff to take out and make your own slaw!)
6) The kaiser roll was fairly good quality, but it was potato-roll style and I would have preferred plain.
Bottom line, if you've got a craving for some NC-style BBQ, this is pretty close to the real thing, which means it's pretty close to the goddamn best BBQ on the planet. I'd bet their other meats are worth a try, too.
Note: I didn't try the reputedly spectacular potato salad, and interestingly enough I didn't see it on the menu. Next time I'll ask.
