The website has no prices listed. How much should I expect to sped for a night of eating and drinking? What do some of the more special bottles run? Is it worth it?
It's worth depends on your expectations. Everyone goes up there expecting to be bathed in cantillon or something.
Food prices are reasonable. Beer can vary but they are pretty much on par with what you'd see at any reputable beer bar. They're a pretty good about offering a decent variety so you can spend as much or as little as you want. The bottle selection is what can really get you with a some pretty hard to find sours and wilds in the $30+ range, but that would be the case in any bar with that selection.
Depends on wether or not you just want a sangwich and a beer or if you're looking to enjoy a full dinner with multiple beers. If the latter, your bill can get steep quickly. Prices are similar to other high end beer bars. Ebenezers is a treat, and generally worth the corresponding price for my very occasional visit just because of its location. If I lived right down the street and went often, I imagine I'd be more senstive to the prices because I could go broke easily there.
Lion's Pride (same owners) in Brunswick posts their updated draft beer list with prices, so go to their FB page or website and you can see what to expect for draft pricing. They have nearly the same bottle list as Eb's, so that may be on there too. Many of the same offerings are available simultaneously at both establishments. As for whether it is worth it or not - it is expensive, but the closest thing to drinking in Belgium I have found in the Northeast. (I cannot afford to go drinking in Belgium, for the record!) Also, lodging in the area is mainly inns/B & B's - there is no camping very nearby except during Belgian Fest in August when you can camp on the grounds.
