So this is what I got, in ranked order starting with the item I liked the best.
1. Lingonberry Almond Cake

As already described above, this is a very good small cake. The texture and consistency are that of a dense, light crumb, similar to a financier, which makes me think there may be almond flour in the recipe. It had a tendency to fall apart while eating it (which is not a flaw in my view).
2. Zucchini Custard Cake

This was a sliced loaf on the counter. It too was very good, moist and dense with a nice light flavor (not that intense in zucchini flavor). As you can see, it fell apart while in its paper bag; it might have stayed together if it had been placed in a box like the cinnamon rolls were, but again, this is not a major flaw to me.
3. Strawberry/Rhubarb Brioche

This was good, although not that different from custard-filled brioches served elsewhere (e.g. Patisserie Coralie), with not much custard and not much sugar finishing crystals.
4. Almond Croissant

This was good, although no different from almond croissants available all over the city.
5. Cinnamon Roll

This was okay, nothing special and not as good as many other versions around town. Some above had said it needs more cinnamon; that's an approach some bakers take, but I don't think it's the only one that makes a great cinnamon roll. (The late Fox & Obel, for example, had the best ones I've had; they didn't overwhelm you with the amount of cinnamon, but rather, did it with a very rich dough.) The cream cheese (?) frosting on top was only so-so and really didn't add anything to it.
6. Baguette

This was very ordinary, although I must admit I am not a fan of a whole-wheat baguette as a concept. I love a great baguette, although the many I've had in recent years have been just okay. (I had a great one recently at a restaurant in DC called Le Diplomate.) But whole-wheat versions lack the flavor and richness of a traditional baguette - and if you enjoy bread with lots of whole-wheat flavor, they're not as good as a really great whole-wheat bread (e.g. D'Amato's).
All in all, I was not overwhelmed; too many items were no different from, and no better than, similar items available elsewhere, and nothing really amazed. I had expected more from his pastries and viennoiserie, given Mr. Schaffer's pedigree and the creativity of his desserts that I have enjoyed at Grace and at Blue Hill at Stone Barns before that. Perhaps as time goes on the variety of the offerings will expand, including pastries that are more unique and more delicious. (As you can see in my photos above, there were only two items in the refrigerated display case and I didn't get either one; the blueberry tart tempted me until I found out it was filled with lemon curd rather than pastry cream.) It's a good addition to the neighborhood for those living nearby, especially with the demise of Swedish Bakery on the next block, but I don't think it's a "destination bakery" worth traveling to from elsewhere, at least not yet. I'll keep an eye on this topic and see if any new items justify a return trip.
