The longtime TGI Fridays on Restaurant Hill in Copley Township has abruptly shut down.

The eatery — one of the original restaurants on the hill off state Route 18 — closed after the end of business Monday.

An employee answering the phone at the Fridays in Green said workers there had no advance notice of the closing, and were fielding lots of phone calls. Some workers from the Copley location apparently are relocating to the Green eatery, at 1039 Interstate Parkway.

The Fridays building in Copley dates to the early 1990s and is valued at more than $636,000 for real-estate tax purposes. It is owned by a California entity.

A message seeking comment was left Tuesday with TGI Fridays corporate office in Carrollton, Texas.

Sit-down chains have been challenged as consumers increasingly opt for fast food and eateries offering fresh, local ingredients.
