Im going to Tokyo next month and I love to try new food.  Can you come up with five affordable (like the price of a typical snack) types of street food I should try there to get the best authentic experience?  I'm okay with weird flavors and textures, but the food has to be sanitary.
Absolutely, here are a variety of five different affordably priced Tokyo street foods:

1. Takoyaki - Steamed dough shaped into a ball and filled with octopus. The outside is nice and crispy, and the inside is a savory and gelatinous octopus. Usually costs around 400 yen, the typical price of a snack.

2. Yakitori - Chicken grilled on a skewer with choices like heart, liver, and thigh. This is a classic Japanese street food and will cost you between 100-200 yen.

3. Taiyaki - A fish-shaped pastry filled with sweet red bean paste. This will run you around 250 yen and is a fun street snack with historical significance.

4. Okonomiyaki - A savory cabbage pancake with a choice of additions like noodles, bacon, and shrimp. This one costs a bit more at around 1000 yen, but the delicious umami flavors are worth the splurge.

5. Onigiri - A triangular rice patty normally filled with kombu, konbu, or salmon and wrapped in seaweed. A cheaper option at 100 yen and convenient to eat on the move.
