Notice the highlighted words and phrases:
When referring to a street, avenue, or boulevard, we use the preposition, “on”.
In casual conversation, you’ll hear Americans say “go up or down the street”.
You can tell someone to “make a left” or to “turn left” (or a right!) and the meaning is the same.
At the end of the directions, you might hear someone say, “You can’t miss it!” This just means that you will see your destination (in this case, the Taqueria), when you get there because it is so easy to see.
