Original Joe's is set to reopen again in Walnut Creek on Wednesday, nearly seven weeks after its big, splashy arrival on this city's dining scene was cut short by a late-night kitchen fire. A spokesperson for the legendary Italian American restaurant confirmed that it would re-open its Broadway Plaza location on Wednesday, though more details were not available Monday afternoon. A staff person at the restaurant said it had begun taking reservations on a limited basis and would have a soft opening on Wednesday.
