Since humans are mostly made of water, and fish traditionally inhabit water, fish should naturally occur in the human body. Fix this gap in nature’s logic with today’s deal. For $15, you get $30 worth of authentic Japanese fare from Wasabi. This Groupon is valid for dine-in meals and drinks at the downtown DC location only.

Wasabi cycles through a seasonally fresh assortment of bold ingredients, which come in plenty of forms beyond the roll variety. Most plates are moderately priced and portioned with the intention of pairing. Start out raw with fresh sashimi, such as salmon ($4) or yellow tail ($5), or snag a more complicated arrangement of wasabi and pork shumai dumplings in a vinegar chili soy sauce ($4). Give any plate wings by pairing it with a four-glass sake flight ($7–$20).

Extended browsing in pursuit of the perfect sushi roll leads to occasional confusion and inevitable neck cramps. Stop pivoting your cranium and let Wasabi Sushi's conveyor belt do the work for you. The conveyor belt provides an opportunity to taste items that had previously just been names on a menu, as well as an opportunity to show off lightning-fast reflexes to a date or sweet-smelling stranger. Using a color-coded plate system to signal price ($2–$5), the sushi arrangements strut down the runway in an attempt to win your stomach's affectionate embrace.

In Wasabi's laid-back dining area, hanging lamps warmly illuminate the wrap-around sushiveyor. Take your seat along the conveyor belt and challenge your dining partner to a game of sushi Skill Crane. Wind down after work by sharing a few Japanese rolls and brews with coworkers; when the last glass goes bottoms up, you might find your dining partners slightly more tolerant of your insistence on using UK spellings, and significantly less hungry.

Reviews

The Washington Post praises Wasabi's superb service as well as the sake:

• The waiters at Wasabi are quick to take drink, soup and extra rice orders; clear empty plates from the narrow wood counter; and ask if there's something you might want but don't see circling on the belt. They also know what they're talking about...Sake is the cool complement to much of this food, and Wasabi pours some fine ones from slender porcelain bottles into delicate matching cups not much bigger than thimbles. – Tom Sietsema

Though reviews on Yelp are polarized, OpenTable users give Wasabi three stars, and five Yahoo! Locals give it four. Seventy-six percent of Urbanspooners recommend the eatery:

• We had a pleasant meal...It would be a good place to take people who are nervous about sushi. – A Yahoo! User
• Fun is probably the best description, although the food is always good and the service terrific. – OpenTable user who dined on 03/29/2010
