Greg Gallagher knows bars -- he owns Gaslamp and the Front Porch -- and he knows the part of town (the edge of LoDo) where both of those bars are located. So he knew what he wanted, and what would work, when he decided to open Roosevelt right next to the Front Porch ? in Writers Square, in the former home of Tryst, which moved a block away. Gallagher says the bar emphasizes mixology and craft cocktails, but with more of a "come as you are" accessibility.
