There isn't any signage noting a temporary closure on the front door. The quick-serve Middle Eastern restaurant's website is still active ... while the phone goes unanswered.
According to a listing at Loopnet, this space has been on the rental market since August 2020 (with an update last Wednesday).
If this is the end, then they've had a helluva run. The current signage says established in 1978. (The previous signage stated 1982!) The space underwent a renovation and name switcheroo from Cafe Rakka to Rakka Cafe in 2013.
Cafe Rakka's Avenue B outpost closed in late 2013.
Yesterday, we noted that Rakka Cafe's neighbors at 83 St. Mark's Place and 135 First Ave. — Stromboli and Dan & John's Wings — were closed due to a gas issue in the building. We're told that there's a separate line for this address.
H/T Steven!
