Re: Liberty Wharf (Jimmy's Harborside)
Being a test kitchen, it would make sense to keep them both open. As long as the demand stays. LTK is a little looser, and hip for the younger and possibly less affluent crowd (I go there from time to time, but am sure I can't afford the new high end flag ship across the street when it opens since it'll be a fish version of Morton's).
While this also helps market across the street when some one asks "do you still have such and such on the menu?". No we don't, but it was so well received that it is available across the street at the mother ship.
