Yep. It's a shack, complete with corrugated-iron roof and plastic windows (during chillier months). And yep. It's rubbing up against the UN Buffer Zone and smack-bang next door to an army guard station. The name starts making sense now, doesn't it. Definitely one of the oddest locations to sink a few beers in town.
If you're peckish it also does decent, simple grilled-meat plates.
