There’s a refrigerated glass case in the middle of the dining room at Rule Of Thirds. It’s full of sake, and you should order some - if only to have something to toast with when someone stands on the bar asks everyone to say, “Kanpai.” This Japanese restaurant in Greenpoint from the people behind Sunday in Brooklyn is a great spot for a fun group meal, and the izakaya food is nothing sensational, but perfect for sharing. Get some yakitori, like a chicken meatball skewer and a lamb skewer, and finish with the huge, crispy tonkatsu. The space is enormous with high ceilings and lots of blonde wood, and there’s a big U-shaped bar where you can hang out and drink a cocktail out of a grapefruit.
