Bad sounding room = bad sounding anything.
Try to not use an "ambient" mic, only overheads that give you the cymbal splashes and the overall drumkit.
You may want to mic only a few inches above the drummers' head, pointing towards the kit. Experiment with the mic positions until you have the snare hitting where you want it in the stereo field (hint : the mics will probably NOT be aligned perfectly to the center line of the kit, but what matters is what ends up being recorded, not how it looks when you put the mics up.)
Cheers
