But I think some cheap restaurants serve very good dishes. I hadn't come to this Udon shop called "Marukame Seimen", but I had heard it had a good reputation.
Do they look yummy in your eyes? As you noticed, all the menu are priced under 500 yen. We have a 500-yen-coin, and dishes cheaper than 500 yen are called "One-coin-meals".
Firstly you have to decide whether you have noodles or rice, and after that you can pick some of these fries. I recommend you choose at least one, as your dish with it will make you full.
The left is Udon, and the right one is a fry called "Kakiage". Normally if you buy a Kakiage at a supermarket, it isn't so big as this. This set cost only 410 yen. What a bargain. =)
The competitions between restaurants get fiercer when we're in recession, but at the same time recession makes them tougher in my opinion.
