Re the "high" prices and heady pour at Local Option:
The Local Option uses proper glassware tailored to each beer, and the glass they use for the Mikkeller (which I had last night) is not meant to be filled to the top. Actually, that's true of most beer glasses since most beers are meant to be poured with a head, and without it the taste and body suffer.
So, you got about a 12oz pour into a Belgian style wide mouth stemmed glass that holds 19oz. Asking to have it "topped off" is not at all reasonable and akin to asking to have an oversized Merlot glass topped off with high-end wine.
As for the $10 pricetag, that is beyond reasonable for what that beer costs them and they are making less profit on it than most bars (including Chicago Ale House) are on most of their beers. All Mikkeller beers are pricey, and that one is over $15 for a 750ml bottle at the liquor store (on the slim chance you could find a liquor store that has it). Add to that the fact that Local Option is paying a premium on Mikkeller kegs because they are the only ones serving Mikkeller on draft in the city (and one the only in the country). I know of people who actually came from Oklahoma recently primarily to have Mikkeller on draft there (I agree that is insane but it highlights just how rare it is).
So, my guess is that the $10 price is less than a 100% markup compared to the 300%-500% markup for most beers at most bars.
In addition, the Local Option has almost nothing but higher end, rare, seasonal type beers that you would unlikely find elsewhere. Whereas a place like Chicago Ale House that goes more for quantity than quality has mostly pedestrian beers that are easy to find, relatively low cost, and often mass produced corporate beers (by which I include their imports that almost all Ambev products). They are making 400% profThis it on a $4 pint of miller lite, so they can afford to charge a little less for a pint of New Holland Mad Hatter. But Mad Hatter would represent the cheapest, highest profit margin beer at Local Option, so they can't lower the price and make it up by selling lots of swill.
Of course, if you don't really care about the rare or high gravity brews and more "run of the mill" (but still tasty) beers like Mad Hatter or Bells Amber are what your after, then Chicago Ale House is likely to have them for slightly cheaper. However, even there you are far more likely to get an old, stale, or even spoiled pint of those beers at Chicago Ale House for the same reason that makes it cheaper and because most of the servers there wouldn't be able to tell that a beer has gone bad.
In short, it's a case of you get what you pay for, with the caveat that you are paying for not only just that beer but for what the bar as a whole has to offer.
