Put the PEP back in your STEP!” ― Hop-Up Soda advertisement
Hop-Up cola is a brand of soda in Rapture, established in 1949. Though commonly mistaken for a bottle of  beer, there is no ill effect to consuming large quantities of this beverage. Drinking soda will restore a small amount of EVE, and splicing the Extra Nutrition line of Gene Tonics will increase the yield of EVE each bottle gives.
Interestingly, this soda could be found in only one place in the first
BioShock, in a trash can in Hephaestus where the game erroneously labels it " Coffee".
BioShock 2 Edit
Hop-Up cola is far more common in
BioShock 2 as a consumable item, and posters advertising it can be seen in many places. Its bottle cap is even seen on the back of the Bouncer Big Daddy doll.

This burst of caffeine from a bottle of soda will restore a small amount of EVE. Like all food and drink, it is consumed immediately when picked up.
