Sushi is but a fleeting moment.

No, really.

About three months, tops.

So let’s move this along...

... to Momo Sushi Shack, a temporary residence for Japanese whiskey and sushi bombs (we’ll get to those in a minute) straight out of Brooklyn, open tomorrow through October at the Mondrian.

Take a look around (this slideshow might help). Yep, still the same beautiful Sunset Lounge. Except upon closer inspection, there’s Japanese whiskey. A lot of it. Gracing the bar. If you’ve deduced that something’s afoot, well, you’re right.

Because the guys behind Bushwick’s eclectic sushi hang have temporarily taken over the space with their sashimi and maki know-how. And they’ve brought a pretty magnificent Japanese whiskey bar and sake menu with them, too.

You’ll be with a date out on the patio, right as the sun is setting. You’ll start with some fried soft-shell crab and seared salmon belly, among other things.

Then... the bombs will drop. Sushi bombs. Hand-rolled balls of rice that are about half the size of your palm and topped with thinly sliced fish. Like the Spicy McBomb with yellowfin tuna and wasabi cream sauce. Then, you’ll get some Japanese whiskey to round out the night. Or maybe go get some ice cream.

But probably the whiskey.
