is bettween pastoria city and veilistone city go down from the enterance of valor
lakefront. it is a big building. that is where the battle cafe is.

Well, do the trainers change each day? And what is it for?

The battle cafe is where lake valor which is blocked off so u cant go in. in order to get
there u must go south of veilistone city and keep going down until u c some trainers.
Battle them that is y my pokemon r high. Then keep going. U will enter this little town
and u will p*** one home then go to the next one and there is a cafe where u can battle.

hey *****s the battle cafe is in the survival area you can fight gym leaders there when
you first go there its locked you have to get through stark mountain toget into it get
your facts straight before you post an answer people

it is in the survival area!

ok all u unregistered people. u guys don't know what the heck your talking about so i'll
just listen to the registered people who make sense.

its in the survival area run by bucks grandfather and you can re-battle all the gym
leaders there. Be warned, they are MUCH tougher than before.

... "After you have completed Stark Mountain's subquest, and watched as Looker took Charon
into custody and Team Galactic's final strike fail. You get access to a restaurant within
the Survival Area. In this Restaurant, Gym Leaders & Tag battle Partners will show up and
will be eager to battle you again."

This place isn't the battle cafe, it's the Top Trainer Cafe. The other one is the Seven
Stars Restaurant "More Flavor Than You Can Wish For" according to the sign. People just
think it's the "Battle" cafe because you can battle there.

If you want to know who you will see there and their exact pokemon, follow this link: http://www.serebii.net/platinum/toptrainercafe.shtml

pokemon games(*cough* Heart Gold and Soul Silver *cough*)...

veilstone city
