The fire destroyed the 6th Street Kitchen this morning at 507 E. Sixth St. The owners tell Eater that "some items in the basement (the chef's toolbox) may be salvageable, but not much else. The cause was an electrical fire in the middle of the night, 'it seems to be accidental, a freak accident.'"
And from the comments:
I live in 507 - The fire appears to have originated in 6th Street Kitchen, and damage is definitely concentrated in the restaurant. Residents were woken by some explosions and the fire alarm, and escaped via the stairs, fire escapes, or the roof. Smoke damage and damage from fighting the fire is fairly extensive, but only the restaurant itself is destroyed. THANK YOU to the firemen and women who responded so quickly and saved this situation from becoming much worse. We are all very grateful.
Meanwhile, DNAinfo reports that firefighters had to return to the scene after marshals discovered a few remaining embers.
The Local East Village also has an extensive report here.
