Don't be afraid of the line that wraps around Maru Kame - it moves very fast. I once arrived behind 40 people and was eating my lunch within 20 minutes. Maru Kame is an udon buffet of sorts. A simple menu outlines basic kinds of udon - hot or cold, egg or no egg, etc. It's great to bring kids along because you can see the whole noodle cooking process as you stand in line, and the udon looks soooo good. After receiving your order, a cook will grab a bowl and toss in a handful of super-fresh, thick udon noodles with your choice of toppings. Next, you move down the line and pick up onigiri, tempura, or inari sushi to supplement your soup - each piece is a la carte, 70-90yen.
Feeling hungry, I selected an inari sushi and four pieces of shrimp and potato tempura. Delicious, and my lunch was only 800yen! The udon itself starts at 280yen.
Mare Kame's buffet-style structure is really fun, and obviously very popular with the locals. Highly recommended.
