The flying gargoyle creatures, called 'Demons', always damage Artyom if you get close. Follow him outside and stay behind the column. Visit the ticket station in the other corner (ammo) and be sure to loot the remains of the body Bourbon was inspecting. Head back to Bourbon when you've done your balcony rounds. Items that you find on a simple corpse will likely not be a cache (there seems to be one exception, and IGN will point that out) however, ammo is still ammo, so if you spot something you can take, take it. These chests are what you are looking for - the caches will be in this form or be clustered in a make-shift home. Ignore the mutant (it flees) and take the items from the red wooden chest (Ranger achievement 1/11).

Head inside, avoid the tripwire, and go upstairs. As he is ransacking the body, turn and locate an entryway near where you came from (the escalators). The first cache is in the room where Bourbon and you start.
