Recommended places for these foods?

Hi all, I would be within Tokyo with a friend. We are based in Ikebukuro and while I generally have an idea of where to go, I thought I would ask anyway. Note that I would prefer somewhere that has English menu, or at least a picture-aided menu, budget is generally below 2500yen per person, but willing to go higher if needed.

Sushi-ya/kaiten zushi: I remembered there was one in West Ikebukuro that offered a flat rate of 100 yen (or somewhere around this price) per serving. Anybody recalls this, or can give a better suggestion?

Ramen: Still unsure where to go for this.

Yakitori: I don't recall seeing any Yakitori-ya on my previous trip, except to have them ordered separately at certain izakayas. Any recommendations?

Tempura: Totally no idea where to go for this.

A general description of where the recommended place to go will be very much appreciated!

Here are a few ideas for local Ikebukuro restaurants: http://bento.com/ra-ike.html

Keishoan (listed in that link) is quite nice for yakitori. It's located in a restaurant complex with a lot of other good budget-friendly restaurants, maybe twenty or so, so it's worth wandering around there to see what interests you.

For tempura I'd recommend Tsunahachi, either the main branch (http://bento.com/rev/0654.html ) or the less expensive branch in Shinjuku Takashimaya.

Another Ikebukuro favorite spot of mine is Rikyu (http://bento.com/rev/3532.html ), which serves quite delectable beef tongue dishes from Sendai.

Some of the recommended places:

Tokyo's Central Wholesale Market
Katsu.. known as Ginza..best restaurants, Isen
Toufuya-Ukai. Near the foot of the Eiffel Tower–like Tokyo Tower.
Tempura:
Before Ginza became the epicenter of Western brands, it was the epicenter of Eastern tempura.

You can enjoy Sushi below \2000 per person at Wakataka in Ikebukuro. This is Tokyo Belt-conveyor sushi bar ranking web site. You can find great sushi bar from price and area.
