Between Pattaya Klang and Pasttaya Nua? Is there a sign nearby that tells me we're close?

When you see the sign for Big C on South Pattaya road then you are "close"

Soi batman has a rather large white abandoned building that looks like a castle, you can see this from the slip road at Sukhumvit/south pattaya rd

I thought it was north of South Pattaya Road - about 200 metres north? Bike shop on the corner.

^There's an entrance to Soi Batman both from South Pattaya Road AND Sukhumvit Road.

Soi Batman

The OP has got the wrong info with regard to location as Soi Batman is between Pattaya Thai (Pattaya south road, Big C) and Pattaya Klang (Pattaya Central road)

Heading north bound from the Pattaya south road Soi Batman is on your left, once you get to the motorbike shops just keep looking for the Soi’s blue name disc and you’ll find it.

If you use the link I posted you will see that the soi has an official number (soi 46/3) now since the street has now been recognized by Pattaya government and actually has been completed repaired compared to a few years ago. Drainage and nice smooth concrete and some new condos and shop houses. The old Bat Cave is still standing as a reminder of the past.
