Found some history in the City Pages:I think this is on topic... The 90's has been around since I was - well it's been around a long time

A quote from a prior owner:
It would be an interesting feature to connect the 90s building to the Marriott via tunnel!!The underground tunnels when we owned the place used to go all the way to the courthouse. When we first bought the bar, we walked through the tunnels.
EDIT: Rats, a further quote:
the tunnels aren't connected anymore across Hennepin Avenue
