Amrit and Amy Gill, co-founders of Restoration St. Louis, hosted the grand opening of Hotel Saint Louis with a Mardi Gras-themed party on March 2, 2019. Guests prayed with Monsignor Salvatore Polizzi as he blessed the restored space before the celebration began. The event featured Cajun-inspired cocktails and dinner stations, as well as a donut stand from Pharaohs Donuts. Mayor Lyda Krewson, and the 2019 St Louis Mardi Gras Queen, Ms. Kitty Kelley, welcomed guests in the main ballroom, where the band Galaxy was playing. The hotel was open for exploring and various sections offered different types of entertainment including Jenn Asia on piano, a fortune teller, palm reader, and magician, while the rooftop bar hosted a cigar station overlooking downtown St. Louis.
