Redwood Restaurant & Bar will not be re-opening.
Bethesda Blogger, Robert Dyer, reported this morning that Redwood has officially closed at Bethesda Row.

The restaurant has been closed since January, with repair work being done on an alleged pipe burst that forced the restaurant to shut down.

Dyer also reports that Thelo Greek Grill (“Thelo” means “I want” in Greek) will open in the old Bistro LaZeez location in Bethesda. Thelo Greek Grill will serve traditional Greek food and is expected to open on April 20th, 2018.
