What do you think are the best foods you can find in Kyoto?

Matcha anything but warabimochi are a big hit in my family.

Not washoku Japanese food unless you're willing to pay a pretty penny for a place with Michelin stars. Affordable washoku there is geared towards tourists and you could get more and better in Osaka for the same price. But Western and sosaku (fusion/creative) food in Kyoto is really good, especially in the cafes.

Ramen

curry rice from cocoichibanya and fried rice and gyoza from gyoza osho

is there any Greek restaurants in Kyoto?

Soft Yatsuhashi!

I don't understand why Gyoza is too expensive. Just 5 pieces for like 500.

It's an unhealthy flour and kept frozen, then fried.

But Dumplings in most Asian countries are quite different to each other.

Chinese Dumplings - Big but Bad

Nepalese Dumplings (Momo) - Fats

Tibetan Dunplings - Oily

Gyoza - Not much stuff inside

Homemade - The Best

McDonald's.
