The Cheesecake Factory is a safe bet for group settings. And you can't go wrong by ending the evening with cheesecake!
This is one of my go-to's when I have a group. The menu offers anything and everything (which can also be a pain in the butt for indecisive people), the portions are HUGE and they offer healthy options with their Skinnylicious menu. My go-to is either the cobb salad or the caesar salad.
And then good luck on only choosing one flavor of cheesecake. There is just about any flavor available. My favorites: Reese's Peanut Butter and Godiva Chocolate... mmm... Honorable mentions for Oreo and raspberry white chocolate.
Service is not super speedy, so be careful if you're on a time limit.
