Don't know why you'd go to obscure place - there is less chance of atmosphere and more chance of a bunch of tv's NOT on the USA game.
I want to find a place with a good balance. Even the obscure places this year have been crazy though too (Miller's Fieldhouse in Doctor Phillips has been standing room only for every match this season for instance). I like a good atmosphere but not when it's full of dudebros who follow soccer once every four years, which is what most of downtown is full of unfortunately. I need to find a place that has the best balance between being full but not douchey.
Finnhenry's seems like a good shout though. It might a good place where it'll be full but not totally packed out, especially with the Wall Street watch party next door, taking away most of the dudes who are more concerned about partying than watching the match.
