Mama Joyce's is the epitome of a soul food takeout place. It's so small that you'll miss it if you don't know it's there, but very much worth taking the time to spot.
For me, the acid test of soul food is the macaroni and cheese, and Mama Joyce's is excellent - like, I ate all mine and wanted to steal my husband's excellent. The yams are also outstanding: sweet with just the tiniest bite of spice to really make the flavor zing. The fried chicken was nothing particularly special, but competent, and the waffles for chicken and waffles light and fluffy. Everything is prepared on-site and very fresh. There are a few chairs to wait for takeout, but if it's a nice day the neighborhood is perfect for a stroll for the 10 or 15 minutes you'll have to wait (a bit longer if you order the dark meat chicken dinner as they fry the chicken at the time of order, which I consider a very good thing).
This is fine comfort food in a neighborhood full of excellent eating. A great addition!
