'Maid cafes' with kawaii (cute) waitresses, dressed as saucy French or prim Victorian maids, are a stock-in-trade of Akiba. @Home is one that's suitable if you have kids in tow. You’ll be welcomed as go-shujinsama (master) or o-jōsama (miss) the minute you enter. Admission is ¥700 for one hour plus one drink order (from ¥570).
The maids serve drinks and dishes, such as curried rice, topped with smiley faces. They'll also play games with customers, like moe moe jankan (rock, paper, scissors). Photos with the maids cost extra.
