You won't find Pliny in Nebraska.
Beer Corner has our best selection (36th and Farnum, midtown). Three bars on site, all accessible through the Moon's entrance. Anyway, Crescent Moon houses the American craft beer. Max and Joe's next door has the belgians, and downstairs is the huber haus, which is a German beer hall. Beertopia, next door, is the carryout store.
We have a handful of brewpubs. Upstream has two locations, downtown and one out west. Nebraska Brewing Company is in Papillion, south of you from La Vista. Jaipur is a Indian restaurant with a small (2 barrel) brew system. Granite City is a chain, which I don't recommend. Upstream is my favorite, Nebraska brewing a close second, only because it's a longer drive from my place.
EDIT:
For an additional packaged selection, you can head across the Iowa border a few miles. The Hy-Vee grocery store near the Mall of the Bluffs (1745 Madison Ave, Council Bluffs, IA 51503) has a good selection of things we don't get in Nebraska. Random selections from Anderson Valley, Bear Republic, Bells, Dogfishhead, and more.
