"good" is insanely subjective so.....here ya go....
this is the one I have gone to and most of my friends (even though I actually do it at home)
its the coin type (is there any other?)
its basically on the corner of Monterey St. and Chrenshaw blvd.
It is on the west side of Chrenshaw and opposite the Torrance main post office.
There is another one on PCH between Calle Mayor and Prospect, on the east side of the street....errr north east... uhhh....something like that
there are a bunch around though...
HAHAAAHAHAAa... I just posted this 1 minute after you! Geee I am so glad I could help...HAHAHAAAA
