There is no one place to recommend in the main electric town. Some shops open and close in a month. Many places are found by accident.
Look for stairs leading down or shops on 2/3/4/5/6/7/8 th floors normaly entered via the ground floor shop.
Just poke around allot and dont be afraid to enter places.

You can always pick up Akiba guides (monthly) that show the location of the Maid cafes or just stand outside Akiba station (elecrtic town entrance South) where the maids hand out flyers.
If you come out of elecrtic town entrance North (facing UDX) look right and you will see Yodabashi Akihabara in the near distance (over the train station) about 5 mins walk.

Go into UDX (3rd floor I think) for the animation shop. They have some area guides and tokyo maps.

Find KFC and turn right (coming from Akiba station after crossing the road) and head down here checking the side roads. Carry on straight down and cross the road bearing left (away from softmap) and carry on down the first street you see (lots of vending machines on the right of this street enterance) just a short walk and you will see Mandrake on the right.
Explore this area for a few mad shops and Maid cafes.
