I will really recommend to go walk to the greenway if the weather allows , is the best experience of downtown Boston a lot of places to see and eat amazing food. Really recommend try Boston clams chowder and lobster roll. Amazing food !!!
See the ugliest city hall in the country! Government Center is a plaza that is often open, but around the holidays, it transforms into a Holiday Village with a skating path and holiday market.
People either love City Hall or hate it. I happen to really like it. This plaza does become a huge ice trap in the winter though. In the summer, this plaza becomes an event space for a lot of things.
