Good way during windy days
A lot better way to get through town.
Great way to get from here to there underground, especially in bad weather.
Mixed reviews from me for sure. On the one hand, I think its fantastic in theory. Its a warm path in the winter, a dry one when its raining. Its a quick place to go where you need to. Theres restaurants, shopping, gyms, bars, and all sorts of stuff hidden away down there.However, there are parts that are ickier than others. It pretty consistently smells like urine or worse, theres a lot of panhandlers, and it gets pretty dark and alone depending what time of day youre down there.Its a cool place to have, and neat to explore, but be wary as you go.
Nothing like walking around the city underground like a ninja turtle.
