TMM left out the best part. It was especially fun b/c it was in a warehouse that isn't usually open to the public. We pulled up to a brick building and were walking down the creepy side, trying to find the right spot. The owner just walked out with a customer and asked if we were there for the Gundams. We went into a side entrance that had the name of the store, plain text printed on a piece of A4 size paper.
He led us through the warehouse that was a shared space - a dimly lit room full of baby furniture, two empty grim "hallways" that looked like we were about to get murdered. The floors were bumpy with thin pieces patched over holes here and there. A crude wooden ladder sat against the wall, near a narrow opening at the top.
The actual Gundam part of it wasn't too bad, better lighting but still with crappy floors. Looked like they were using it for personal storage, too. There were zombies, a Frosty outfit, a really old typewriter, and other random things strewn about the highest shelves. No music, just shelves and shelves full of build kits and tools. For a bit we were the only ones there, but it felt better once more people showed up.
