OSS follows its natural energy; the five stars doesn't mean its the best restaurant, rather it is a great example of the style. Simple, fun, relaxed.
Creative brat combos at a reasonable price with some nice variety, but not to excess. Beer taps are limited but good (esp. Karben 4). Decor playful Steampunk vibe. The bun is too big, but it is fresh and they're working on it. We live in walking distance and hit it up one a month for lunch. Perfect nap fuel.
