What an interesting mix of answers. It appears that there is a very even split of people who eat a lot and those who eat out very little. About 60% of people eat out $25-100/month, while 25% of people eat out $100-200/month. But 4% of people spend over $200/month while 8% never eat out at all.
I guess it depends on where you live, and what point in your life you are. The lifestyle choices are probably shaped due to interesting circumstances. I know that Fabulously Broke in the City a guest poster, lives out of a hotel room without an apartment. Because of this I can guess they eat out more than average. But they save tons of money by not paying rent or mortgage. A very neat lifestyle.
I am rather impressed by the results of the poll. It seems not that many people are indulging in eating out as polls of the average americans would claim.
