I have visited Harper's a few times in the past two years. The restaurant is clean and inviting. The atmosphere is warm and personable, which is nice for couples and families.
But with each experience, I am less impressed. The food is good. However, there are better places to dine within the Southpark area. The food is moderately priced, but is too much for what you get. My last gripe with the restaurant is the limited menu. The offerings are scarce for a restaurant with a nonspecific specialty. I'm not big on chain restaurants, but I would have been happier visiting The Cheesecake Factory located across the street from Harper's which has many more menu options.
I am sad to say that I will not visit again unless an executive group decision is made to dine here. : /
