FOOD - I eat stuff all day long and it is the one thing I find to be the best as far as perks. Above all, keep it all free or have some kind of 'honor code' pay container where you have a bunch of snacks, drinks, etc and employees could give 50 cents for a soda, juice drink, or whatever. There are other things like bringing fruit or vegetable platters for afternoon snacks when it might be a longer day than most.

PERSONAL PARKING SPACE - I know this is really not doable in most circumstances, but I HATE coming to work a few minutes late and not having any place to park.

FLEX TIME - Some companies have flex time where you can work lots of extra hours this week and next so that you could take a few days of next month.

Whatever you do for perks, I think it is vital to make your employees feel appreciated. Sometimes just telling them 'great job' on stuff can go a long way.

Just another thought, how about asking your employees what perks (within reason) they would like. Ask what would make them excited to come to work and not want to leave.
