The snacks are awesome. Seek them out if you want local food and non-tourist prices. I am a big fan of Divi Divi Bar/Snack. Not to be confused with the Divi hotel. Their soups are awesome and the specials always rock. Mariachi night is a blast.
Divi Divi Bar & Restaurant Bonaire
Hong bar is okay for cheep beer but not much else. It won't be $4 for a bright though
As mentioned above Maicky Snack is great as is the Rose Inn. I am a big fan of doing a drift of La Dania's Leap > Karpata, lunch at Rose Inn and then Candyland, Tailor Made. To me, that is the perfect day on Bonaire. Maybe top it off with a beer at the lookout point on the way back to town.
Here is a list of a lot of them.

Rose Inn, yes! I think of it as a restaurant, not a "snack," but I suppose if it has no more than five tables, it would qualify. We have never managed to do an afternoon dive after lunch at the Rose Inn. A few Amstels and we're done.
I'll look out for Divi Divi. It's not impossible we will say "Oh this place, we've been here!"
By the way, your link to the list of snack bars is the same one the OP included.
