___ Fridays

TGI

This casual dining chain's name starts with the initials you'd say when relieved the workweek is almost over.

This clue references the popular restaurant chain "TGI Fridays," where "TGI" stands for "Thank God It's." The answer is the abbreviation commonly used in the name, so you just fill in the missing letters before "Fridays." It’s a straightforward cultural reference—no wordplay, just recognizing the well-known brand.
