I'll do this in two parts:
As a venue:
I've been to two shows at Foundry, and both times it brought me back to a simpler, less encumbered time in my life, when I was a sixteen year old going to my friends' shows and listening to too much 80s punk and metal. Drink prices are extremely reasonable and the staff keeps the environment optimal.
As a restaurant:
Went for wing night. Will go again. I cannot for the life of me figure out why there isn't a line out the door. Quality at a perfect price.
