There are three kinds of street food. One is beaver tails, another is Brussels waffles, and the other is stick food. Which food do you like the most and why do you like the street food?

I like beaver tails the most because they taste sweet. I like Brussels waffles because they are thick and have large pockets and we can choose toppings such as chocolate, ice cream and fruit. I like stick food the most. Especially I want to try fruit sticks. They look yummy.

Would you check the passage and correct errors? Thank you.

There are three kinds of street food. One is beaver tails, another is Brussels waffles, and the other is stick food. Which food do you like the most and why do you like the street food? It seems odd to ask why the other person likes stick food if he/she has not indicated that it's what s/he likes most! This is one good reason why we should NOT put two questions in one sentence!

This part is fine, but the second sentence seems a bit too long. Can you condense that one?

The passage appears to be correct with no grammatical errors. Well done!
