read moreRhymers, OKAY / OJ / OBEY / OSHEA / AU LAIT at the ends of themers. Bonus points for ending an entry with a J. That ...FOJ string looks so neatly bizarre! AU LAIT was an interesting one too, tougher to uncover than the others. I was expecting an O' somewhere (Cafe O'Lait = Irish coffee?).

Rhyming words have been mined for many crosswords, so it's important to go above and beyond with some extra layer. Here, I like Sam's tightness, nearly covering the solution space of O-?AY rhymers. The only other ones I could think of were OIL OF OLAY (oil of au lait?) and ANITA O'DAY. Something elegant about using a complete(ish) set.
CAFÉ AU LAIT is a great entry in its own right. MILO O'SHEA is definitely crossworthy, although he might be on the cusp of what an educated solver (especially a newer one) ought to know.
GLASS OF OJ … I hesitated at first, as the phrase didn't feel solid enough for my taste. But it's something I've said at diners, so I'm not sure why it didn't strike me as strongly as CAFÉ AU LAIT.
I had the same reaction to IS THAT OKAY. It doesn't feel like something I'd strive to work into a crossword. YOU WILL OBEY left me with the same feeling. Maybe I haven't been to enough hypnosis acts?
Audacious layout. I said DEAR GOD to myself when I turned up ETES and ESS within seconds of starting the grid — neither is friendly to beginning solvers. Thankfully, OTHELLO and TEA CADDY felt worthy of those prices.
KLATCH might be a toughie for newer solvers, as might be MALA fide. And the crossing of URBANA / AVEDA could be a trap that takes away a solver's feeling of accomplishment … if they guessed URBINA or URBENA I would be sympathetic. All in all, I would have preferred a grid layout that didn't push the Monday boundaries so much. Breaking up the four corners more would have been my preference.
Overall though, I appreciated that Sam gave us something a little more than a standard rhyming theme.
ADDED NOTE: Glad I read Sam's commentary! I didn't realize the short-short-short-long pattern of syllables! That's a neat extra layer. Wish there had been some revealer in the grid to point it out.
