Here's a tidbit, pending the organizers' report: I found the role of starch in this cuisine to be really interesting.
It seemed that people order the type of starch and then, secondarily, think about the accompanying meat, sauce, or vegetables to be served with it.
Sometimes the starch was served on the side and sometimes it was plunked down in the middle of the plate, absorbing some of the flavors. Aside from Iyanze, it didn't seem they were used to providing silverware to their regular diners. This is really eat with your hands type of food, which I found challenging sometimes when we were served soups.
At least two of the restaurants have hand soap on the table and bring you wash basins so you can clean your hands before eating. Clearly, there is no expectation you'll be eating with a spoon!
To top it all off, the starches really did vary from place to place. While they may share common ingredients (yam, cassava), their were some marked differences in flavor - probably due to fermentation. One fufu smelled and tasted of sourdough or beer.
There is a lot to this cuisine other than starches, but those were some of the observations that stuck with me as the day wore on. You'll be hearing (and seeing) a lot more about other details of our meals, I'm sure.
All in all, this was a pretty fantastic afternoon spent familiarizing myself with foods I had never before tried. We definitely went to some spots that I will be returning to.
