Mooo is a Beacon Hill steakhouse that has a dining room filled with modern art, a big wine cellar, and a six-ounce wagyu sirloin that cost $185, so it’s pretty much what you imagined when you first read the words “Beacon Hill steakhouse.” The atmosphere isn’t quite as stuffy as it could be, though, thanks in large part to a more relaxed bar area. Mooo is a good option for a special occasion, or random night when you want to feel fancy.
