@RyanRadia @JustinLawGuy @breathtkinan @NateSilver538 US restaurant sales are about $800 billion. That's about $2400 per person. Some is take out. Average cost per meal, I don't know, must be kind of low given all the fast food. Let's say $20. If half don't go out at all, that would be 5x per week. Your estimate is plausible too.
@RyanRadia@JustinLawGuy@Breattkinan@NateSilver538美国餐厅销售额约为8000亿美元。每人大约2400美元。有些是外卖的。考虑到所有的快餐，我不知道每顿饭的平均成本一定有点低。比如说20美元。如果有一半人根本不出去，那就是每周5倍。你的估计也有道理。
