Business Dinner Reccomendation

Hi, I will be hosting clients for a business dinner and would like restaurant recommendations. Looking for a nicer place that is conducive to conversation, but not a ritzy steakhouse/wine type of dinner. Around 15 in the group, so bonus points for anywhere with a private dining area that could accommodate. I know I could do the usual Pappadeauxs, etc. but looking for other options as well. Also, trying to stay more on the southern half of the city. Thank you for any help!
