So, if I can identify this font that would be great, but I'm guessing that it's a custom job, so if I can find something similar, or even samples of similar stuff that isn't font based, or EVEN just somewhere to start looking for inspiration so I can start from scratch myself, that would be awesome.

The main thing I want to replicate for a logo job I'm working on is a fun retro script, that doesn't look like it's trying really hard to be retro. The thing I like most about the Grill'd logotype is that the variation in width across the typeface is very subtle, and not overly calligraphic.

Their website is http://www.grilld.com.au/ if anyone wants to look deeper into it. Any pointers leading in any direction would be much appreciated!
