Good Kansai-ben/Osaka-ben phrasebook
This is basically a phrasebook for 大阪弁. Every phrase shows the 標準語/東京弁 and 関西弁 versions, and then the same example sentence in both dialects. There was a lot more 丁寧語 than I was expecting, and also some of these phrases are I think very こてこて - at least I've never encountered a number of them in any of the media I've consumed, or conversations (with teachers from Osaka) I've had. I imagine it would be different if I actually lived there though.
Anyway, setting that aside most of it is standard, quite useful vocabulary. So it's a great book to own or read through, imo
