The Lion’s Chorus is a brewery which can act as an open floor bar if needed.

As for Hercules knowing about Sleeper's identity; Hercules was completely fooled by Sleeper's disguise. Though Loki probably saw through it. I would certainly be in favor of Loki incentivizing Sleeper to make more public appearances by saying something like "You're not the only purveyor of false appearances. I know what you are. Come to the festivities if you want to keep your status quo."
