I was impressed with Boquiera, it's not a rip off in the slightest. Courtesan is also great, really interesting menu and excellent cocktails.
A restaurant bill is about time, relaxing, good service, not washing up, new experiences, a vast range of ingredients otherwise unaffordable / unattainable, and good company. Don't sit in a restaurant price-matching the equivalent weight of food from a supermarket then moan about it on the internet. That's pretty weak / low.
If you're just hungry, get a takeaway.
