Jackson Square Overlook

Jackson Square Overlook is a location in Gabriel Knight 1 located southwest of Jackson Square on the top of a building.

Behind the scenes
Contrary to popular belief, "Jackson Square Overlook" is not Washington Artillery Park (which lies across the road from Jackson Square to the south), but rather is a lookout platform on the roof of the Jackson Brewing Company ("Home of the JAX Beer"), a building southwest of the Jackson Square, to the west of Washington Artillery Park.

The lack of proper name of the location/building is probably to avoid copy right issues, as the game uses fake company names for several foods/drinks in the game.
