you may have seen an uncle sam’s, either in oakland, squirrel hill or at the waterworks. you may have thought that it’s a chain restaurant with it’s thorough decor and teenage staff. the only thing that may have tipped you off is the fact that they only take cash. uncle sam’s is a locally owned and operated business offerring yummy subs to several parts of the city. you always get a foot-long and they offer thin fries as a side [included when dining in]. for me, a foot-long portabella sub is two meals, and for a total of $7, that’s a deal.
