With a friendly barrista staff, Mama Java's is one of those coffeehouses you immediately feel comfortable at. Good coffee with a nice, unassuming atmosphere, including a real comfy couch which you can sit back and relax on. Free Wi-Fi and live entertainment on most nights (eg. bluegrass on Sundays, open mic on Tuesdays) are big pluses, too.
Definitely a positive attribute to the Arcadia neighborhood.
