This is in a mall that I like. An out of the way place with good prices and lots of great lunch choices.
This is a very playful name to give a mall's food court. That the "t" is made into a tree proves that they're playing on the word "forest." Whether they believed that forest is spelled with two "r's" I cannot tell you. On most days, I'm not sure myself, although I believe that "Forrest" is a man's name and not a place full of trees.
But they're having fun with English, that's the main thing. If you think that something is fun, and interesting, it's much easier to learn.
