In a world without sushi, chopsticks would only be used for such simple tasks as playing the xylophone and performing open heart surgery. Bring the wooden chops back to their roots with today's Groupon: for $16, you get a sushi lunch and drinks for two at Blue Fin Sushi Bar & Restaurant on East 29th Avenue (up to a $38 value). The lunch includes:

• Any two sushi rolls (up to a $26 value)
• Two Sapporo beers, two glasses of house wine or sake, or two soft drinks (up to a $12 value)

Sharing more than 30 years of combined experience among them, Blue Fin's three sushi chefs stitch fresh ingredients into savory, flavory dishes. Every day, Blue Fin flies in fresh fish from all over the world to create rolls, such as the Caterpillar roll, with slices of eel and cucumber curled into a cocoon of rice, eventually emerging as a beautiful butterfly adorned with specks of soy sauce. Other rolls reflect the variety of the chefs' French and Japanese training, from the 29th Avenue roll's spicy tuna to the House roll's baked salmon and yellowtail. Patrons can wash down sushi rolls with 12-ounce bottles of Sapporo beer or glasses of Mirassou red or white wines. Wisps of steam from brewed rice waft from glasses of house hot sake, while nonalcoholic soft drinks challenge even the most confident chopstick wielders with their stubborn, slippery ice cubes.
