Have you tried Amazon? They have an amazing selection of international foods.
Lu (the Belgian biscuit manufacturer) also makes a Petit Beurre that might be available in your local supermarket - they have pretty wide US distribution (usually in the imported foods aisle rather than the cookie aisle)
Not the brand you are looking for but Kedem Tea biscuits found in the kosher aisle of most major supermarkets look very similar. You use the word crackers, so I'm not sure if the ones you are looking for are sweet. Kedem are considered sweet but definitely very mild. Like I said, not what you are looking for, but may work as a replacement.
I tried Cost Pus World Market, and Trader Joes. As well as the import section of the supermarket. Didn't find anything like the petit beurres or choco bananas, or choco oranges.
So I went to Euromix.
Here's what I got (see pics):
I was really hoping to get the choco bananas, or choco oranges. But they didn't have anything like that.
I think the biscuits in the lower left corner, in the tan wrapper, are close to the petit beurres.
And I think the chocolate covered gingerbread strawberries, in the upper left corner, are kind of close to the chocolate bananas, or chocolate oranges. Interesting that it's made by Kraft, but with a foreign brand name.
Those wafers with the cherry filling in the upper right corner look interesting too.
And lastly, in the lower right corner are the Cookies Dream. I took a separate pic of them, because I thought it was hard to see through the wrapper.
I also went to 99 Ranch.
They had Petit Buerres, but I didn't get any, because I already got some biscuits from Euromix.
So far, I've had the chocolate strawberry hearts. They are good. The inside is spongy, with a mild strawberry flavor.
Last week, I went to Euromix.
This week, I went to European Market and Deli, which is in Castro Valley.
Here's what I got:
* Top left corner: Lemon flavored marshmallow-filled chocolates. These seem similar to the marshmallow-filled choco bananas that I posted about in the OP.
I think there were only 1 or 2 varieties of the marshmallow filled chocolates. I forgot what flavor the other marshmallow-filled one was, but it wasn't banana.
They had other jam-filled chocolates (lemon, blackberry, strawberry).
* Biscuits: The biscuits last week were "with baked butter aroma". These biscuits this week are "with baked milk aroma".
* Kinder chocolate box: These contain 8 bars. It says
" + Chocolate
* Kinder Bueno Bar: This one says "Milk and hazelnut".
So overall, I think I found the type of things I was looking for. The suggestion to check out European markets was on the right track.
This European Market and Deli had all of the items I got from Euromix, plus these marshmallow-filled chocolates. So that was nice.
Small correction: Top left corner chocolates are not made with marshmallow filling. Here is the info, according to Wikipedia ( http://en.wikipedia.org/wiki/Ptasie_m... ):
Ptasie Mleczko "...is a soft chocolate-covered candy filled with soft meringue (or milk soufflé)."
Sorry to be so picky, but Ptasie Mleczko is where most of my excess fat comes from and I would hate to have it from eating marshmallows rather than meringue ;)
