I don't recall ever seeing this mentioned, but Original Rinaldi's which has gotten some love in the past opened a branch in late 2009 in Manhattan Beach. The place is run by Laura (Billy's wife) and old time Rinaldi's customers will see Mikey there too with some other familiar faces. The menu is similar, but they do have some sandwiches unique to this location. The Manhattan Beach location also bakes some of their rolls onsite too (I think it's 3 types: squaw, honey wheat and italian white). They also feature some soups too. I found out they have a website that has info about both places. http://www.theoriginalrinaldis.com/in...
I think the hours posted are for the El Segundo shop. I believe the hours are slightly shorter for the MB location. I got a sort of "bahn mi" sandwich (which you can see on the "monthly special" header of the website) at the MB location.
