This is the most important intersection in all of. G street (Ave de los Presidentes) is a major traffic hub and a fantastic place to meet people. During the day there are thousands of students in this area since it is so close to the university. At lunch time, the paladares (restaurants) in this area are filled with people. At night, the open air bar at the corner of 23 and G is filled with people drinking, dancing, playing music and having a great time.
