I could not parse the NW corner, which took over two minutes of my total time. It certainly didn't help having DELWEBB and ALDO Gucci next to each other. More to the point, I had ISm at 5D: Suffix with human (IST), and that threw off the theme answer.
Fortunately, I finally recognized PATHE (shouldn't have been so hard; when you have PA_HE, how many letters can go in there?), and the rest fell. 1A: Thing on a string (BEAD) - I tried "yoyo" first. The actual answer is fine, and the clue is cute. I'll give it a B.
I like three of the 7-letter down answers (all except the one in the NW corner). OTTOMAN is good, especially referring to Suleiman rather than a piece of furniture. And in the opposite corner, STPETER opposes the advance of the Empire. They didn't quite make it to Vienna, but their influence was felt in Mozart and Beethoven's Turkish marches (I love that section of the ninth symphony, and not just because it's a tenor solo).
Also in croissants, which may or may not have been developed to celebrate turning the attack away.
By the way, we ate a ton of croissants while we were in Paris recently.
Um, anyway, the crossword puzzle. I wish we could do away with YSER and SNERD. ULT seems particularly ad hoc. LBO stands for leveraged buyout. Whatever.
It wasn't the best Tuesday, in my book.
