Hah! Interesting name "Gacoan" that could mean a lot of things. It could mean "Jagoan" (hero) and also "No Profit". The word "Coan" in the Chinese Hokkien dialect means "Profit", so GaCoan (play in word) could also mean Gak Untung (No Profit). It must be a very popular hang-out joint for students and youngsters.
lmao that's probably what they actually meant by those name. Also yes, it's quite popular and all that, convenient place, cheap food, 24/7, just everything students/youngsters need.
