Difference between Not in the same street and Up another street

not in the same street—(coll.) not nearly so good as smth.; much inferior (also: not in the same league):

• Although the fruit is sweet it’s not in the same street as an edible delicacy.

up another street—(coll.) quite another thing:

• You want a few details…. That’s about what you want; but giving you the information is up another street.
