Mad46 - The Roosevelt Hotel, located at the corner of Madison Avenue and 46th, reaches new heights once again with the reopening of its rooftop lounge mad46. Guests are invited to kick back, relax and enjoy a refreshing break from the hustle and bustle of the "city that never sleeps" atop the 19th floor of a legendary landmark hotel. The mad46 lounge opens its skies on April 15, after a winter hiatus. For two weeks in April, mad46 will be open Wednesday through Friday from 5pm to midnight. Mad46 will be back in full swing Monday through Thursday from 5p.m. to midnight and Friday 3pm to midnight starting the first week of May. New indoor space will also be available perfect for rainy afternoons and escaping the summer heat. Happy hour enthusiasts in search of slightly more substantial fare simply shoot downstairs to sample The Roosevelt Hotel's own palate-pleasing dining experiences.
