Taps Restaurant in Brea, California has a great Irish Red--the wife's favorite!!! I earn points when we go there.
Great Lakes Conway's Irish Red has probably been my favorite so far. I think I've had Sam Adams Irish Red somewhere along the way, but I don't remember. I generally enjoy most of Sam Adams stuff, but I have the feeling it won't top Conway's.
If you have a Claudaugh Pub chain around you. They've had it on tap for a few moths. I had my first in Ireland too and spent years looking for it over here.
Oops... looks like I was premature with the "Delete" option over there on Imgur (I hate when that happens).
I just brewed and bottled an Irish Red. Will be ready to drink 1 week before St. Patty's Day! So hopefully that one!
