Oktoberfest has come and gone, but a number of restaurants and sandwich shops still seem to be running burgers and other items based on the German beer festival. I’m not sure why. Maybe they’ve been surprise hits. Maybe the restaurants are looking for a better return on special-order ingredients. Whatever the reason, as long as they keep offering Oktoberfest burgers, I’ll keep eating them. This time, let’s talk about Steak n Shake’s version.

The fact that Steak n Shake isn’t offering a beer milkshake to pair with is a serious oversight, I’ll admit.

The Steak n Shake Oktoberfest Steakburger tops two patties with Swiss cheese, sliced ham, and onions sauteed in spicy mustard, all on a pretzel roll. I was very impressed. I’m always a fan of adding ham or other meats to a burger, and both times I’ve ordered it they’ve been pretty generous with the slices. The real standout, though, is the onion and mustard mix. I’m a fan of spicy foods, but primarily in the context of a spicy flavor, as opposed to heat for heat’s sake (the kind of thing you get with hot wings, a lot of the time). This was somewhat hot, but in a different way than a burger with jalapenos or other peppers. Spicy mustard is really underused on the fast food/chain scene, and it was a welcome addition. The pretzel bun was decent but unremarkable, I doubt it’s one they’ve used before. All in all, a great sandwich.

The Oktoberfest Steakburger runs for about $5.50 with fries, slightly more expensive than the average Steakburger. However, it’s well worth the price, and I would highly recommend having one before they disappear.
