Hanny's is a swank bar where you can lounge around and get good drinks. If you go there with those expectations, you will love it.
The food is good, but if you're only looking to eat, Hanny's wouldn't be on the top of my list. However, if you want something to supplement your third scotch, their food will more than suffice.
Go there with good friends, get a corner booth (with reclining backs), order a barrel-aged manhattan with some pizza to snack on, and you'll be set.
