First is Mago Grill & Cantina (which we noticed back in November) and the second is Regus:
Dallas-based Regus Group leased 17,000 square feet of second-floor space in the property at Roosevelt Road and Wells Street, a spokeswoman for the company confirmed.
We've heard the name of Regus, but don't know much about them. According to wikipedia:
Regus plc is a multinational corporation that provides serviced office accommodation in business centres. As of 4 April 2014, it operated 1,800 business centres across 100 countries.(Hat tip: TO!)
