Plans are already underway to expand both floors of the popular Upper West Side restaurant Prime Ko. They have taken over the location of their neighbor and they will be extending their first floor Prime Ko space and adding a Burgers/ Hot Dogs/ Sports Bar concept with a great beer and drinks menu downstairs, under the name Prime Burger with a totally separate entrance and phone number. They are set to open April 1st when we will publicize their phone number and website. But stay tuned as this is just developing.
