Street parking in front of and in the surrounding area of the venue as well as multiple parking garages with accessible parking spots. More info on the venue's website.
It is a small area directly next to the stage that is blocked off by barricades, security will escort you to the area and no one is allowed in there except people with disabilities and people with them.
There is a balcony but to our knowledge only has stairs to get to and is significantly more expensive, it is marketed as a "VIP" section, so tickets for that section cost way more than GA.
There are bar stools but we're unaware if there are regular chairs.
The venue's website says: The Forge is ready accommodate patrons with disabilities. Please email firstname.lastname@example.org with your name, all pertinent info, and event. Prior notice is preferable for your convenience. We can accommodate last minute requests. Please stop by the Box Office upon entering and request a manager.
