a sight to behold

cliché An especially impressive, noteworthy, or remarkable person, event, or thing; something or someone who is very much worth seeing. If you never go anywhere else in your life, make sure you see the Grand Canyon: it's a sight to behold. The new jazz singer is really a sight to behold. She's probably the best we've ever had at the club. That lavish new hotel is really a sight to behold. I swear, you'll feel like royalty when you're in there.
