Quite amusing to read of the menu options in Portland. Here in the UK our biscuits are your cookies, not a great mix, cookies and gravy, with or without "red bits"
I noticed something called a "Reggie", again, I have no idea what that is?
I have visited Portland a couple of times, staying in the HI Hostel. One advantage of hostels is that you can cook your own meals, and there is a wholefoods type shop quite near that hostel. One of my favourite US cities!
Enjoying hearing about your trip, so few folks travelling these days!
