Many restaurants charge a 'cubierto' fee. It's a table service charge and most times includes some bread, butter, still water or maybe a little extra (tiny cookie at a cafe, etc) or a lot extra (glass of champagne and sauces at certain steakhouses). It's common and, with inflation, I guess $1,500 really is on par with what amount it was years ago. Some restaurants ditched the cubierto charge but raised menu prices so, who knows.
For me, $1,500 when I'm choosing to go to a full service restaurant to eat isn't terrible, but this also doesn't go to the staff that serves your table, it goes to house. It's been customary in eating establishments here for as long as I remember. If you're concerned, I'd ask before ordering whether they charge a cubierto and how much it is...so you can dine accordingly but not be upset with the business for charging a fee that's quite normal and customary here.
The restaurant business is a tough one and many places are struggling to stay afloat now that costs for their rent, sourced food, electric bills...are skyrocketing. I try to be cognizant of that and go to places I really like, to support them so at least the fee goes to a place I really enjoy, in hopes they adjust to uncertain inflation and stick around. A small price to pay to keep places afloat in this uncertain climate. It's been hard on a lot of people living here, dining out is far less accessible but when I can, I like to support those institutions.
I don't want to see this city devolve into a landscape of chain restaurants and look-alike mini malls.The independent businesses here really contribute to the allure of the city. But, again, no shame in asking the fee before being seated so you can dine elsewhere if you'd like to avoid it, as plenty of places have just folded that fee into menu prices.
