Buildings need to serve multiple purposes, they can't simply be built for a single purpose. The more purposes a building serves, the higher the likelihood, in my opinion, that it will be successful. New buildings downtown should be built to these specifications:

1. Partially underground/aboveground parking ramp.
2. Retail on the first two floors of the building directly connected to said parking.
3. Offices/hotel/residential/institutional on the higher floors - with a "tower" lobby in the first two floors mixed with the retail.
4. The retail sections on the first two floors should accommodate future skyway connections to other buildings.
5. Provide ample sidewalk space - for establishment to have a sidewalk presence - i.e. Eateries, etc...
