First the good things about the bar. There is live music which is good and there is ample outdoor seating. The food is good but not excellent.
The bad things: The waitress is extremely rude. She refused to give us a beer menu and asked us to just go to the bar and take a look at what beers they have. She took a long time to service at the bar. So I get some beers, tip the waitress at the tip jar and later she comes outside and shouts at me saying that I wouldn't be getting any beers unless I tip her. I told her that I'd complain to the manager and that I did tip her at the tip jar, to which she said she didn't care and walked away. They have a bad beer selection too.
I am never going to Iron Post again and wouldn't recommend others to go. There are other very good and hospitable bars close by.
[Edit] The waitress I was talking about sent me this message at yelp. "Dude, stay in the library. You obviously don't understand the idea of cool. You parents will be proud of their engineer loser son."
