Go for the takoyaki balls with the rice crackers (that works as a tidy takoyaki sandwich) and the one without rice crackers.
Otherwise, they have decent cheap udon with seaweed. The udon was a bit too overdone but it's fine for the price. There's no air-conditioning and it's located in the back of Village by the Grange (which by the way has some of the best cheap-eats in town). I went there on a weekday for a 1pm lunch with about 6 coworkers and we were seated without a hitch because it was after the lunch rush.
The takoyaki competes with those at Kenzo Ramen. The ones at Manpuku are smaller and it's the only place I've seen with the nifty rice crackers.
