It is location dependent. It also depends on what you like to eat.
Much social life goes with eating out. Friends of my GF invited us to a steak dinner at a class downtown place, and a local rep theater afterward. Our meal alone cannot cost less than $150 -$200. I checked the place out for a birthday dinner for GF and figured $250 with appetizer, wine and tip. I cannot get on this merry-go-round, so we will recip with a nice home meal and good wine.
Better more attractive food in more attractive settings is going to cost more. A lifetime of experience will affirm this. But when I am alone and just want a hunger postponement of some enjoyable food downtown with water to drink, I can do this in one place I like for <= $10.
If I get lunch that I like, pleasantly served, for GF and myself for $45-$65 in my neighborhood I'll feel like all is well with the world. Life is short, and besides, what I spend on pleasure the stock market cannot capture from me. We sometime split the cost, and sometimes I buy. If a man is dating, he'll spend a lot on spinning his wheels with sometimes annoying women. It is my pleasure to spend some money on a prize.
Interaction with other people can be abrasive. Some of that can be mitigated or avoided by spending a bit more to upgrade the physical and human surroundings.
