Signature Theatre Stage Door

So I was curious where the stage door for Signature Theatre is. I am seeing 'Signature Plays' tomorrow. I have never been to Signature Theatre and I am thinking there are more than one stage?  I believe it is playing at The Alice Griffin Jewel Box Theatre. I was told the stage door was just the upstairs lobby?

Thank you for the info!!

When I saw the show last week, nearly the entire cast was out in the lobby before the audience left their seats. I didn't hang around to see if they were signing, but just be aware: it seems like they tend to leave quickly. 

And just to be clear: the actors were exiting from the  doors near the Griffith Theatre, NOT by the bathrooms. Those doors only lead to the backstage area of the Diamond Theatre.

That could be. When I saw the show last weekend, they were coming out of the side doors near the Griffith, by the little bar area over there. By the time I made it from my seat to the lobby (no more than 3-4 minutes after curtain), Frank Wood, Phyllis Somerville, Crystal Dickison, Alison Fraser and Sahr Ngaujah were already either in the lobby area or in the process of exiting.

Not in costume. They were in street clothes. 

When I saw Girlstar there the cast used that same exit and they were in the other theatre so I'm guessing that's the main way out. Some go down the stairs where we came up and some walked to the left and used those stairs to leave.
