My company put us up in Mishima, a small city that acts as a transport hub for the tourist mecca of the Izu Peninsula. I wandered around for a bit, but there wasn't much to see in terms of noodles.
Then I found Bird Bar. Occupying a corner wedge near the south side of the station, this little standing bar was packed with attractive young guys and girls, all who were stopping for a quick drink before starting work. Work at 10pm? Let your imagination run wild.
One stylish lady on her way to a job at a hostess club recommended Haruchan for a 500 yen bowl of tonkotsu ramen.
Sure, this works. These countryside ramenyas are always a decent way to end an evening of drinking.
Not worth a trek, but check them out if your company ever puts you up in Mishima.
