The latest cosplay themed café to appear in Akihabara is set to provide a full Code Geass: Hangyaku no Lelouch experience; Café Geass will offer cosplay service, with all staff portraying a Geass character, as well as a fitting menu of food and drinks to match the milieu (presumably something vaguely British?), and each character.
The café, Café Mai:lish, is actually a maid café keen to branch out, and the Code Geass theme will be a temporary one, operating this month from the 19th to 21st, and the 26th to 28th, for a total of six days, so fans of cosplay, themed cafes and Code Geass will need to be prompt.
You can see their staff (maids) on this page, complete with 2D illustrations.
Given the popularity of Code Geass, it might almost be able to sustain a dedicated café (surely if miko can manage their own café, Lelouch and company can too), though the maid boom seems to be quiescent for the time being, so now might not be a good time.
Still, there is always the Code Geass AV to look forward to, if merely being served a cup of tea is not stimulating enough for you.
