I've been to Chubby's twice now and am surprised by Porcupines experience. (I posted a review of a meal I had a couple weeks ago on roguefood.com if anyone's interested)
Not all BBQ is all things to all people, but Chubby's does a great job, in my opinion, of serving quality smoked meats and letting the customer decide whether they want a Carolina style sauce, or southern, etc. The brisket is exceptional. Other than a couple samples I've had at BBQ competitions and in Texas this is great beef.
Sounds to me like a lot of P's issues were more a matter of personal taste. Vinegar issues etc. Personally I have issues with overpriced bait, so I stay away from sushi joints.
Also, meat will only fall off the bone when it has been overcooked, and if it's overcooked it's going to be mushy.
Overall my experience with Chubby's is that it is a very good BBQ joint that features genuine home style cooking that is reasonably priced, in a very unlikely location. (5 minutes from the Mason Dixon Line)
I'd be interested to know where Porcupine usually goes for BBQ to have a better perspective.
