As for pairing with Stouts and Porters (which are essentially the same, since first there were Porters and then extra stout Porters, though by now some differences have come out, mostly that a porter usually is smoother, maltier, sweeter, and not quite as dark, though you can hardly pin it all down) I would usually go either with something dark chocolaty, be it just chocolat, or truffles, etc. or a really nice and hearty dish like some pork of beef dish ouzing heartyness, unami, and a bit of sweetness.
You are gonna get a big mouthfeel with roasty notes, dark chocolat hints, and some coffee, on the canvass of a round maltyness. Full, indulgent, and drinkable. That is kinda the baseline expectancy with all porters, so you can imagine pairings too. Their chocolate and coffee porters are obviously geared towards that while the normal one will be more malty in that great roasted grain way, which imho goes extra well with savory meals.
I really envy you for being able to get those great American IPAs and other beers fresh. When Stone open their place in Berlin I will rejoice so much (but that is still a long way out). Especially the possibility of getting Pliny the Elder (or Younger) fresh and stuff like DogFish Head 60min (I dare not even dream of the other numbers) is like a dream to me. Finding a DogFish Head here is like Christmas. Raison DŽetre I have had before, even a Bourton Baton. The India Brown Ale I will open soon and when I got a 60min once it was....wow.
In the US you can always look for Mikkeller beers though. While he is a danish brewer, I live right over the water from Copenhagen in Sweden where he has 3 bars now, he is the godfather of Gipsy Brewing so you have a chance of finding his stuff everywhere. Also one for insane beers both in concept and intensity. Makes over 120 different beers a year IIRC. Also a big buddy of the insane Three Floyds, who must also produce stuff for you.
He is the creator of two of my favorite beers ever, the Frederiksdal Spontancherry, a sour cherry lambic that is 10 times more intense than anything I have tasted thanks to the guys from Frederiksdal who make the worlds best cherry wines. And then there is Beer Geek Brunch Vanilla Shake, an Imperial Oatmeal Stout packed with vanilla. Brilliant.
In the same vain but more drinkable is his estranged brother who goes under Evil Twin Brewing. Also a gipsy, but he is now based in New York where he also has a beer. Had an Imperial Doughnut Break Stout he did and oh my...
There are a lot of other great craft brewers in the US, some of which I had the pleasure of meeting at the Copenhagen Beer Celebration, but have a look out for Mikkeller and his Evil Twin. Amazing and weird stuff.
