Moody's Falafel Palace has always been all about the food. After all, this not-so-hidden treasure in Central Square is an intimate spot, to say the least. Housed in a miniature tower of white porcelain brick - a relic of the White Castle hamburger chain - the entire restaurant is about the size of your bedroom. With an eating area not much larger than a king-sized bed. Meanwhile, an incongruous mix of faded awards, still-life prints of flowers, Mediterranean photography and newspaper clips hangs on the walls.In other words, what Moody's lacks in spaciousness, it makes up for in character - and value. The prices and service compete with nearby fast-food joints, and the food is, some say, better for you.
