I have included a pic of the existing logo. We are located at 18 Orange street, which explains the orange and our new name. It would be cool to keep the orange as it is a neighborhood landmark. (photo quality orange) 
 
Another option is to get a coffee cup in the logo, possibly use the curved handle as a C for the beginning of Cafe? 
 
I doubt we can mix the orange and coffee but any ideas? 
 
Can we add the little mark above the e in Cafe?

Thanks for all the hard work. The logo looks great! Very original and unique ideas!
