We recently visited their other location in Aventura (we hesitated, because we never enjoy the one in KB), and that's when we realized that the KB location, with the same menu items, is average at best. The food in Aventura was really good, yet the exact same dishes are not even close in Key Biscayne.
I live and work in Key Biscayne, so I guess that I will end up going there again. It is not "bad" but again, there are better options. But if you are in the Aventura area, try the one there!
