This is something that will be interesting to observe if it is organized well. It's so unfortunate that, the continent with the richest cultural values is gradually losing these values.

One time we had a church harvest themed "cultural harvest", the planning community organized it so well that the different tribes represented such as yoruba, igbo, hausa, idoma, Edo and so on, prepared dishes for sale that other tribes can buy and have a taste.

A month or two ago, there was a festival like this organized by a chief in Ghana here. The turnout was not encouraging though
