FWIW the Senator lounge in B is open (B45 I think). It was significantly less crowded than the Senator lounge near the A gates.
And yes, absolutely nothing to write home about in terms of food offerings. I'm somewhat puzzled that restaurants have found a way to operate in the airport but the lounges still can't seem to get their act together.
Honestly at this point I'd just eat the McDs in the Z intercontinental pier. All of the food I've eaten outside the FCLs/FCT never really outperformed a hot order of french fries and chicken nuggets.
