If you are a fan of the Costa Rican national team, you will not have a problem Friday morning finding a place to cheer on the players.

Every bar, every restaurant and even in front of the giant screen at Avenida Central and Calle Central will be friendly territory.

But suppose you are for the Germans?

It might be a good idea to confine your cheering to a place hosting like-minded fans.

One such place is Colegio Humbolt in Pavas near the U.S. Embassy.  The Institución Cultural Germano Costarricense has invited present and former students, faculty and the entire German community to watch the game on a big screen. Information: 232-1455 Ext. 223

At the Club Alemán in Los Yoses, Volker Fink, the German ambassador, has invited diplomatic corps members and other special guests to come early at 9 a.m. for a  ceremony.

The German Embassy also reports that in Ciudad Colón the Asociación de Desarrollo Específica para el Rescate Histórico, Arquitectónico y Cultural del Cantón de Mora will host a Tico breakfast and a German lunch after showing the game. Information: 249-3124.

AutoStar Vehículos S.A., the Mercedes dealership, has constructed what is being called a virtual stadium at its La Uruca facilities.

The company promises a party atmosphere with models, drinks, food and even raffles for air tickets to the United States. Information: 295-0004.
