Having stayed there, I can give you more details if you like cowboyneal. Just shoot me a PM.
The simple stuff :
It's close to Belnem, and we picked up tanks from Photo Tours (first trip at their Caribbean Court location, last trip at Port Bonaire, on the other end of the beach by the airport). Marcel was working with Photo Tours / Dive Friends to set up tank inventory on-site when we left after our Thanksgiving 2006 visit, so that may be a done deal by now. The 'free upgrade to nitrox for nitrox certified divers' at the Photo Tours Port Bonaire location worked great for us!

The house reef is the Corporal Meiss dive site in the Schnabel & Swygert book - they evidently founded Photo Tours, as some of my older books have their names in front of "Photo Tours" in the business name. Most of the photos in my 2006 trip gallery were taken from our dives on the house reef there. The old scientific research grid right at the dropoff is a perfect navigation aid, day or night. Many of the pics were dusk dives that we enjoy - the slipper lobster was bigger than a shoebox!
There are restaraunts in the Belnem area, or just on the other side of the airport and Caribbean Court - Chibi Chibi with Divi is probably one of the closest, and there was a place by Lisa Car Wash called Gibi's. Anyway, after Chibi Chibi there's loads of places to eat all the way through town (Cactus Blue & Donna & Georgio's were our favorites on our 2006 trip). There's also a (some?) restaraunt(s) on the road to Sorobon as I recall.
Marcel at the Bellafonte can set you up with extra discounts from Photo Tours and AB Car rental through their concierge service as well. This worked great for us.
My wife's U/W pics from our trip are now in my gallery - she's working on the above water ones. Got great shots of trupials, either the Bonaire parrot or Parakeet (we're still debating / deliberating - the external differences seem subtle to us), and some interesting weaver bird nests at Port Bonaire when we dropped off & picked up tanks.
For us, the location is just right - we're not 'party animals', so the distance from live music etc. is a plus for us, but the convenience of town and the southern dive sites is right there if you start up your truck.
The drying room is roomy enough for everyone for both of the visits we made.
North sites are still reachable - the green moray eel pic was a dusk dive at Andrea II for example - good size, around 5 feet long, and we had the site to ourselves for that dive.
