Yeah, ya know, right after I posted, I googled, and Wikipedia actually had a picture of exactly what she described!
So bangers aren't that much different than regular old pork sausage? I think we'll go with that...but she did say that 16 of them are $9. I was really surprised she could even get them, but they are nearby at the "real" butcher shop in the city. She said they make them there, and that they are as good as she's ever had in the UK. But expensive, so if they're not that different, I say serve something cheaper! 
Yes, free, but not exactly. She did our team pictures and for that we charge a vendor fee of 10% of her profit. Instead of writing me a check, she'll have the breakfast.
I think all the guys would find it unique but not inedible--except for the black pudding. I just can't get past that personally, I guess, but I don't see the harm in offering it. I think I will publish the menu in advance so they can be prepared.
Still can't wait to hear from the UKers.
