Head right and travel through a door into an overgrown kitchen. Climb up, then teleport across through the open elevator door. Luckily the elevator shaft has some ladders in it that you're able to climb. Oh well, time to find another way upstairs. Press the red button to activate the elevator, only to find out that it's completely inoperable. Lift the painting and complete the circuit inside: Follow the conduit all the way to another junction box inside the wall, covered by a painting. Get on top of a nearby crate if you can't reach the top of the doorway. Activate it with your Multi-Tool and follow it along the doorway. You'll find another sensor next to the door that you originally entered the foyer from at the beginning of the level. Now, head back into the dining hall and then back into the foyer. Follow the conduit along the wall with your Multi-Tool and switch circuits in the following order: Stick the battery inside of the battery compartment, then activate the sensor in the electrical cabinet nearby. A fourth Resin can be found in this room, inside of a nearby filing drawer. Directly across from it on the opposite wall is a shelf with another two Resins hidden on it. On the first shelf on the right as you're coming through the door is a box with a Resin inside. You'll immediately see a battery compartment and a locked container. Heading back out of the bar, take a right and open the door to the maintenance room. Walk back to the bar and find two Resins plus a battery hidden inside. Kill them, then take the shotgun shells from the piano on the opposite (right) side of the room. In the main dining hall, you'll encounter a headcrab zombie and a headcrab that burst forth from the bar on the far left side of the room. Shoot the barnacle in the foyer for a pistol ammo clip. It will scurry through the elevator shaft in front of you and shut off the power nearby, forcing you to find an alternate source of power to get the elevator running again. Take a right into the foyer and you'll catch your first sighting of a lightning dog, a headcrab-like Xen which electrocutes everything nearby. Inside the one on the bottom right is a Resin. Turn around and immediately in front of you is a set of filing drawers.
