Wow! Dirty Bastard is a favorite, this French toast bastard is new to me, however. From your description it sounds like freaking heaven on a Saturday morning. I don't go out much to sample the pub offerings as often as I used to...working in the commercial refrigeration field, I have seen (and SMELLED) so many "under-maintenanced" draft systems.
But the great news is, you have just encouraged me to embark upon a quest to find this brew and drink it! Good stuff. Thanks for sharing this one.
