I spend in Medan only one day and I cannot say I enjoy it. As another big cities in SA it's very dirty and smoggy. People though wasn't pushy and even-though we walked during night I didn't feel danger. .
I have visited Medan twice and this one of three largest metropolis in Indonesia never turned me down despite of its famous hectic and chaotic traffic. Besides rich for its wide variety and delicious foods, one thing that I like for Medan is the richness of culture since the city is home to well blended various ethnics, which makes it interesting. Moreover, this city is a start point to various beautiful places in the North Sumatra and its surrounding.
Medan is the city you will start to another tourist place like bukit lawangto see orang utan etc
What a beautiful place as Lake Toba is here. Here got more Chinese and mostly businessmen. The local cake and kuih is very delicious.
