Dill pickles

A street restaurant that only sells pickles? I reckon you didn't read the OP. It might work in Portland Oregon with cute name. The city of shops selling quirky things and/or ONE thing. Anyone for JUST TAMPONS?

Never been to Oregon but they must eat anything if a pickle cart would be successful. My comment was meant to have the pickle option to an existing sandwich cart. Maybe your tampon idea will be a success, good luck.

There was a pork guy on Soi Khaotalo once that did a raving business

If its the guy down near the diamond factory ..........he is still there and still busy............ normally 5 or 6 people queueing and he is gone by 9-10pm..........lovely neck pork he does.....
