I eat at Harris' all the time. I don't even MEAN to, I just happen to end up here a lot. I think it's because it's the kind of place that lots of people can agree on - pretty good food and drinks and a KILLER patio. For me, the patio kicks it up from 4 to 5 stars. in the winter they don't serve lunch. In the summer this place is hoppin' all the time and yes, I'm that jerk hogging a giant table waiting for my friends to show up - they're just PARKING.
(speaking of parking - don't park in the lot next door you WILL get towed!)
None of the other reviews mentioned yet that they recently changed the menu - one of the great new additions is the BBQ pork sandwich. I love it in slider form - get the coleslaw with it and stick it on the sando. delish. I don't even LIKE coleslaw - including on a primanti's bros sando - so you know it's good.
The mac and cheese (add the andouille sausage!) is a staple and you can get a mini version as a side to an entree for just a little extra.
Another new addition is the chicken fried bacon - yes, you read that correctly. It is a hearty plate of bacon that is battered and fried and comes with white gravy. I've shared it 3 times with friends and each time it's been a little different but also kind of left me a little queasy although with a happy novelty food feeling. I would definitely not recommend one person trying to eat this unless they were trying to commit suicide by bacon - which I also don't recommend - and I LOVE bacon.
Overall I love this place and I don't think the drinks are more expensive than most of the other places on Ellsworth - half price frozen cosmos are definitely worth it. Service is also usually great.
