Virtual zone is a great cafe, it could easily become the best on the island in a few easy steps :
1. Upgrade ALL the pcs... not just a handful in the back, put in 9600s/6200s and maybe more RAM .
2. announce 'Gaming hour' where no surfing can be done , have clan wars with bigger prizes in parts and cash ( 3 or more times the pcs= 3x the profit). Though this should be done only when you regurlarly have the entire cafe full .
3. allow BYOC ! make space for 3-4 pcs in the front row , leave monitors and keyboards and announce BYOC for the same price (maybe a discount) as normal cafe time . People will bring l33t machines that look great , play next gen games like Doom III and Riddick to show them off , and attract attention ( be sure to give them REAL big screens in front , and hook one up to the monitor in the showcase as a clone display ) . IT will be kinda like wallerfield for technophiles .
