I've been to Hanny's a few times, mostly just for drinks. They have teeny weeny martinis for a price that something so small should probably not cost. I've often thought they may have bought these small martini glasses in the kids section of Ikea. They must have been confused.
I think the space is pretty awesome and has a very clean, crisp feel to it.
I enjoyed the vegetarian pizza when I was there last and thought it was mighty tasty. I'm not a big dough fan, so the flat bread is perfect for me. At $11 a pop, I think it is a pretty decent value. I'm generally a fan of pizza and paninis so Hanny's menu does not bother me (like many have noted).
If you can put up with a smaller than normal size martini, Hanny's is totally worth a shot. However, beware non pizza and panini people!
