There is NO lounge in BJ that I would consider shelling out cash for. Internet is free throughout the airport, regardless. The food in the lounges is mediocre at best. Outside the lounge, the food options are not fantastic, but not worse than the lounge. The airport is rarely so crowded that one can't get a seat outside the lounge. The only possible reason is to have a shower, but I think one can even go to a 'rent a shower' place.
