Certainly! Here are the corrected errors in the passage:

1. "Beaver tails" should be "fried dough" or "Beavertails" (a type of Canadian pastry).
2. "Stick food" should specify the type of food on a stick, such as "skewered food."
3. "A long odeng and a flat odeng" should be "a long odeng or a flat odeng" to indicate a choice between the two.
4. "A bungoeppang" should be "fish-shaped bread" or "bungeoppang" (a Korean pastry).
5. "A Brussels waffle" should be "a Belgian waffle."
6. "Walk out from the school gate" should be "Walk out of the school gate" for proper phrasing.
7. "Across from the stationery store is the famous restaurant" should be "The famous restaurant is across from the stationery store" or "The famous restaurant can be found across from the stationery store."
8. "You can see a stationery store on your left" should be "You will see a stationery store on your left."

I hope this helps!
