Parking was rough when I went last time. There's no parking lot so I ended up parking 3 blocks away. That was Friday evening after 5pm.
If you can't find close street parking, park near bay meadow park, and walk a few blocks.
Parking on the street, hit and miss
There's street parking on Delaware street and on parallel streets near fieldwork brewing company. Usually it's not very difficult to find parking although weekends can get busy, so you have to hunt a bit.
