I was very fascinated by this place. The underground city is one continuous mall that spans 7 metro stations in the downtown area. Famous for its endless shops and boutiques and a sanctuary for those who seek to escape the unforgiving summer heat or the bitterness of winter, the underground city is an interesting way to get around the downtown area, great for grabbing some quick eats and window shopping some famous stores. Admittedly, it is very easy to get lost in here - once you've ducked into the maze that is the underground city, it's hard to tell where you'll end up. Although, there are semi-helpful signs posted everywhere to point to essential streets and metro stations to make sure you don't stray too far from your destination.
