Totally off topic (well, it's about lunch) - but do all tech companies in the US order in lunch every day? In Australia at most companies we'd "go out" for lunch - even if it was just wandering down to the sushi takeout place to stretch the legs.
I've moved to Paris now where (in the traditional parisian style, I guess) at least a few times a week it's group meals at nearby restaurants.
Nowhere I've been do people "order in" food - unless it's a late night pizza run. What's the reason that it's so common in the US that it can support a (cool looking) service to do so?
