As the taxi drivers huddled around bar windows, deftly ignoring anyone wanting to go anywhere, they watched as the cheers went up, firstly, for those in blue and yellow and then red and white.
However, it was the River fans feeling relieved at full-time having seen their team draw 1-1 at La Bombonera.
After a lousy run in the Copa Libertadores (down but not out), utter failure last season and an unconvincing campaign so far, River fans are finally beginning to lose their patience.
Palermo bags opener
In the biggest game of the season, it was an ecstatic Martin Palermo who edged Boca ahead after 59 minutes in front of an even more elated crowd.
However, Marcelo GallardoÃ¢ÂÂs 25-yard free-kick soon put an end to the celebrations.
Ã¢ÂÂWe could of won it,Ã¢ÂÂ coach Nestor Gorosito said afterwards, or something similar. Ã¢ÂÂRiver finished with a good image. I would have liked more of the ball, and not lose it so quicklyÃ¢ÂÂ¦ we had few chances that meet our potential.Ã¢ÂÂ
Boca, without the injured Juan Roman Riquelme (who will also be out of their Libertadores clash with Ecuadoreans Cuenca on Wednesday), remain in 13th position.
Under-performing they may be in the domestic league, but this is a team who have been together for several seasons, have some talented youngsters at their disposal and have a proven, but not stellar, record.
Elsewhere, Velez leapfrogged Lanus and Colon to top the table. However, Huracan are fourth, their highest position in years, giving this correspondent reason to be slightly over-excited.
OK, they are still five points behind Lanus but Los Quemeros havenÃ¢ÂÂt had too much to cheer about for, well, lets just say a long while. They walloped bottom-of-the-league Argentinos 4-1, each one of them a GOOOAAALLLLAAZZZOOO.
