Grill 23 & Bar vs Mooo
Grill 23 is Back Bay's independent dry-aged steakhouse since 1983; Mooo the Beacon Hill room. Book Grill 23 for the steak.
The Verdict
Grill 23 is the steak. The Back Bay room at 161 Berkeley Street has run independently since 1983, with marble columns, white-jacketed service and a 45-day dry-aged programme that the kitchen treats as the point of the place. The dry-aged ribeye is the signature cut and the most-ordered dish across four decades, and the beef arrives with the kind of crust that only long ageing gives. Cuts run from the low eighties to a hundred and fifty dollars. It scores 8 for food, 8 for the room and 7 for value.
Mooo is the hotel steakhouse. Columbus Hospitality opened the Beacon Hill room inside the XV Beacon Hotel at 15 Beacon Street in 2007, and it reads exactly as old-money Boston expects a steakhouse to read: low light, deep banquettes and a quiet, moneyed hum. The bone-in ribeye and the truffle fries are the orders the regulars place without looking, and the wine list runs deep and expensive. Cuts sit in the same broad range as Grill 23, with the bill nudging higher. It scores 8 for food, 8 for the room and 6 for value.
The split is independent versus hotel. Grill 23 is the proudly independent Back Bay institution where the dry-ageing does the talking; Mooo is the polished Beacon Hill hotel room built for a discreet, expensive dinner. Both are power tables. Grill 23 is the better steak, Mooo the quieter room.
