Hi Teddy, 1. Where we have breakfast (you don't need AT). 2. It's about 3 minutes walk ( you could avoid repiting "away from here" as you already mentioned it in the previous sentence). 3. Then take ABC street, which is the third (street) on your left OR Then take the third on your left, which is ABC street.

Teacher 1: This morning, I walked to that vegan restaurant where we usually have breakfast, but it was closed. So I kept walking to see if there was another vegan restaurant nearby. Luckily, I found one about 3 minutes walk away. Teacher 2: Where is it? Can you show me how to get there? Teacher 1: Sure. As you walk out the front of our school, turn left. Then take the third street on your left into ABC street. Keep walking for about 10 steps. It will be on your right.

I kept walking ahead --> I continued walking, I kept on walking P.S. It's easier to provide corrections if you post in the "Notebook" section.

Remove the word "at" from the first sentence and everything is fine. You can remove "it's about 3 minutes walk away". However many natives; do add in these extra little bits of information into natural conversations. It's what makes them more interesting. Some natives say "take the third street on the left". or "take the third on the left" <-- thinking you will know it is obviously the third street/road/walkway etc. or "go third on the left" <-- using the same logic. "take the third street on the left"<-- is standard and plain no ambiguity. It is a natural sounding conversation. Well done.
