It is a tour that combines a tour of Harlem with a visit to a church where you can hear a gospel choir. Meredith, our guide, was very engaging. Too bad these gospel choirs are mostly a business. If you organize yourself, you lose a bit of historical information, but you can visit an Abyssinian Baptist church where everything is very local. There is a dress code to enter, the mass lasts 3 hours but surely you can see the true soul of harlem. Personally I spent most of the hour inside the church, watching the few locals how they behaved, how they were dressed. It's still a good experience
