This is the real thing. An original. In business for more than 100 years, Rudolph's looks like a meat market should--big and echoing--and has enough fine aged beef and sausage on hand to gag a tiger. In the long L-shaped counter are strip steaks and made-on-the-premises sausages that are wholesaled to barbecue joints across the state. The filet mignons--cut as thick as you want at $18 a pound--bring your backyard grilling up to four-star standards. The hot dogs and spicy sausages make you swear you'll start working on that diet next week.
