For "mom and pop" type restaurants, which we call "snacks" on Bonaire, I would also like to recommend "Mi Banana, as well as El Fagon Latino..they have great soup, Julio's right in town is excellent for a burger, or local food like goat, chicken and beef stew, make sure to ask for it 1/2 and 1/2 and you will get a small salad and 1/2 rice and 1/2 fries. Maiky Snack, which is in the middle of nowhere, (on the road to Sorobon) is great. I also second Rose Inn...IMHO, the coldest beers in town!
Also, Tuesday night is Gibi's night...he serves family style meals at his house...now talk about mom and pop.... EXCELLENT!
