Unlike visiting a new neighbor’s house, visiting a steakhouse comes with a virtual guarantee that you’ll be welcomed, fed, and trusted with knives. Make a hunger-halting house call with today’s Groupon: for $50, you get $100 worth of steak, seafood, and drinks at The Prime Rib on Calvert Street.

Distinguishing itself as one of Baltimore magazine's Best Restaurants in 2010, The Prime Rib invokes the memory of elegant 1940s Manhattan supper clubs with its tuxedoed wait staff, opulent dining room, and extensive menu of succulent steaks and fresh seafood. Prime palates with appetizers such as the maine lobster bisque ($9.95) before rising to larger-portioned plates built on USDA Prime steaks in a range of sizes, from the 8-ounce petite filet mignon ($40.95) to the 12-ounce New York strip ($42.95) and the 12-megaton Las Vegas Strip.

Patrons can delve into marine territory with the chilean sea bass, in which a vieille maison sauce of tomatoes, onions, and capers lovingly drapes itself over the deep-water fish ($32.95). A round of cold-water lobster tails stuffed with imperial crab (market price) nests savory crustacean flavors, and a platter of marinated and grilled jumbo shrimp ($28.95) suits classic seafood tastes. Sweeping selections of side dishes, including au gratin potatoes ($7.95) and grilled artichoke hearts ($9.95) accompany an entree on one hand, while the entree's other hand juggles a vast selection of vintages from a nine-part wine list without spilling any on the tablecloth. Complete a cut of meat or fish with anything from budget-friendly libations by the glass to a Prime Rib feature wine from the house recommendation list.

Black surfaces embellished with gold, stately table settings, and a baby grand piano highlight The Prime Rib's upscale atmosphere. Guests draped in business-casual attire gather in plush leather booths that afford a prime view of live piano and bass music sessions. Filled patrons can migrate to the fully stocked bar to sip classic cocktails as they try to revive the Rat Pack, only to realize that nobody has a passable Peter Lawford impression.
