I've been to Harris Grill many times. My favorite thing is their happy hour -- half off all drafts, frozen cosmos, and wings from 4:30-6:30 PM. I'm happiest if I just stop by for a couple of brews and wings. The strawberry chipolte wings are great -- I just love the flavor of the sauce. It's not too spicy but very good.
Aside from happy hour, I've had very mixed experiences with the food there. Sometimes it's been good, other times it's been overcooked and/or bland. I've also had some fairly slow service there but nothing bad enough to stop me from going back.
It's definitely a place worth checking out (you guys be sure to take a stop in the bathroom while you're there... I hear they have a very interesting urinal), but I tend to stick to bar food/brews when I go.
