None of the rooms had the bar in any obvious spot, but despite that there were undoubtedly zombies outside hunting for you, there was no banging, not even the sound of moaning. It appeared that they had given up, for now, and you had achieved momentary safety. 

Each room that you peaked into was a simple room with a stretcher a desk with some equipment, and some chairs. In one room, the furniture was merely left messy and out of order, but in the other, the stretcher seemed to have been pushed out of the way from someone who entered, and the chairs had been thrown around. On the counter was a scalpel dripping with blood that also stained the counter.

The third door out in the hall was locked, but must have been some kind of office as it was right behind the counter. If there were any more efficient weapons or clues to what was going on, it could be in there.
