Wow! That looks pretty interesting. Too bad the pizza didn't have much flavor though. Maybe the waiter was thinking "who orders chips with pizza? This guy is shady" and that is why he kept looking at you :) We had a bank that was turned into a restaurant down the road from me. They had a private dining area in the old vault and you could reserve it for a special experience. It has long since closed, and I never went there, but I always thought the concept was kind of cool.
