Been going to the Iron Post for about a year now and can say the bar is great. They have a very knowledgeable and friendly staff. The Post has a good selection of beers and decent bar food. The live music is good and really creates a great atmosphere.
As for the reviewer below, the Post has a beer menu. They set bottles of all the current beers beer behind the bar, that's their menu. And people who usually have to defend tipping, usually don't tip.
In short you can't please everyone. If you want to go to a place that isn't pretentious, with a knowledgeable staff and like live music, the Iron Post is the place to go.
