If you are a regular about town and usually get around by bicycle, then you may find this route the easiest.
If you know the The Rock Aussie Sports Bar (formerly the Red Rock) in Sakae, it's real easy.
Exit the Rock and turn right. Desperados is on the very same street. It is about a nine-minute walk (much less on a bicycle). You will cross under the expressway and keep heading straight. Desperdos is about three blocks past the expressway, on the right-hand side.
If you don't know the Rock, shame on you, it's a great place. Stop in for a beer and a meat pie sometime. But if you don't know it, the street you want is the street just behind the Chunichi Building, parallel to Hirokoji Dori.
