I grew up in Sioux Falls, SD and still go back there to visit my folks at least once a year. In college (Augustana), I drank a lot of beer, but it was all basically the same kind of beer. My fizzy yellow water of choice was Old Milwaukee because it cost $5 a case, and you got part of that back when you returned the bottles. Occasionally, I would try an "exotic" beer, which at the time meant Corona, Moosehead or Becks, but I usually stuck to what was the least expensive, but still drinkable. Even if I had been more adventurous or knowlegable about beer at the time, I couldn't have found much variety. I knew one store in town that carried Guinness, but that was it. Even well-known imports like Bass didn't make it to Sioux Falls at that time. 

Things have certainly changed and now Sioux Falls is a beer oasis in the upper Midwest. They don't have a brewpub now (Sioux Falls Brewing shut down years ago), but many local beer stores have a nice selection of regional craft brews alongside the usual American Pilsners. One store, though, really stands out -- Taylor's Pantry (at 41st and Minnesota). It's a gas station, but it also has a beer selection that includes a wide variety of Belgians (including several Cantillon lambics) along with the Midwest micros. Their biggest strength, however, is in Scandinavian beers. They have beers by Nøgne Ø (Norway), Haand (Sweden), Huvila (Finland), Mikkeller (Denmark) and others. Taylors also recently started selling homebrewing supplies and are consulting with the local homebrewing club (Big Sioux Brewing Society) to meet the needs of local homebrewers. 

The beer selection at local bars is highly variable, but many of the better bars and restaurants have at least have a couple local micros on tap. But again Sioux Falls has one standout -- Monks (on 8th street, downtown). As you might expect from the name, Monks carries a lot of Belgian beers. And, they have a decent selection of Belgian glassware, so you won't end up drinking your Trappist ale out of a Shaker pint glass. They also have plenty of regional micros. I tried a Surly Furious -- a double IPA from a Minneapolis, MN brewery --there and thought it was fantastic. 

So, if you ever find yourself in Sioux Falls and were expecting it to be a beer desert (as it was throughout the '80s and much of the '90s), you'll be happy to discover that an oasis has formed there.
