I've been to IPH a few times, and I really like it. While the menu isn't large, and sometimes it takes me a while to decide what I really want to eat, I still think it's one of the more interesting places to eat in Pittsburgh right now. The burgers really are exceptional.
Where it rocks is with the drink menu - if only time, money and inevitable drunkeness weren't an issue!
I'll be back, but I also look forward to the menu continuing to evolve.
