I ran first and got a pastry from Pane Ho Baretta, a d'Amonde Chocolat (?). Definitely good but heavy, as expected, and pretty messy, as there is chocolate on the outside. They had a lot kinds of d'Amonde, though just a few of each on display.
Just from Googling, I had found Le Pan as a cake source in Kobe. I've probably seen the sign pointing upslope on the lateral road between L'Avenue and Gregory Collet Patisserie, but assumed they just have cake. I got cake for later before putting the borrowed bicycle in working order and going around photoing shops for
Kobe Patisseries map, being maybe less discriminating than I should be, since there are places that I seem unlikely to visit, though a note to that effect might be useful later.
The cakes were Saint-marc Praliné and Tanba Chestnut Mont-blanc. The saint-marc was good but did not stand out. The supposed mont-blanc was the third cake in that many days that was not much like the conventional form, or like any other. This one actually had very little paste, though there was a little more chestnut inside. The main body is rum cream. It had very nice flavor and texture, so I'll say it was excellent.
I seem to having a lot more luck in this second pass through Kobe cake shops, though that may because I've sticking closer to the central cluster rather than visiting every neighborhood shop that managed to get in a guidebook. I'm also willing to visit the old brands, like Juchheim, sometime, even though I consider them fairly low-level brands in Tokyo. Like Tooth Tooth, I'd like to at least give them a chance in their own shops (though, actually I don't think I've seen any Tooth Tooth cakes in Tokyo, just they have a French restaurant).

Another day in Kobe last Sunday and had cake for two at Grégory Collet, which has moved north and exchanged being a café for being a modest salon de thé. We'll miss the lunch menu, but at least there are a lot of interesting restaurants around there (which we wished we had taken advantage of rather than trying to eat at the hotel at Shin Kobe Stn.). 
The last one, called Segur, was Bretagne salt caramel in a milk chocolate tart. It was definitely good and met my sweet tooth. If I judged more on appearance, then perhaps I would rate it better but I really don't cake what cakes look like beyond what it reflects about the construction. Fortunately, my foot had finally stopped hurting (I hadn't been running through Sunday, but still did more walking than I would just commuting to work).
Went to Factory Shin in Kobe as a café (just drink and cake sets). It's modern and frequented more by young people. The selection is still fairly traditional in the sense of being the simplest standard cakes of Japanese cake shops, but they are good. We had the Mont-blanc and the Strawberry Shortcake. The Mont-blanc was definitely good, but nothing unexpected or exciting except maybe the meringue base, which is fairly thick and very sugary (I would guess just sugar and egg white, versus an almond powder based meringue), which is a good thing. Also, I should note that while this was the most common type, a reverse mont-blanc (i.e., the "blanc" is on the inside under the brown chestnut paste crown), there is candied chestnut in the center.
