Another thing i would love to try is Casa Marcelo, just a few steps from the cathedral and recommended in this book from the rubberman. However on my first time in Santiago I did not know about it, and the second time i did not know the right people to appreciate it (it costs a bit more than the average place unfortunately). And I will under no circumstance have a sit down meal by myself if i can avoid it.
I had a wonderful solo dining experience in Casa Marcelo when i was volunteering in SdC in 2019. After finishing my shift I decided to pop down and check out the place as had noticed queues out of the door most lunchtimes. I was awaiting about 20-30 minutes to be seated, reading the menu and had decided by the time they came to seat me that it wasn't a suitable place for a solo dinner. I explained this and they said it was absolutely no problem, they would tailor the servings for me. The chef came out to chat, checked did i have any good allergies /loathing (i eat almost everything, struggle with offal) and very memorably asked me did i trust him... I'm so glad I said yes! I was treated to a magnificence meal and i never knew what was about to be put in front of me. If i recall correctly, an oyster to start then the most zingy amazing tomato-y tomato salad, steak tartare, a fabulous dessert. It was absolutely fabulous, a great memory and dining solo allowed me to fully concentrate on the food. (and people watch/eavesdrop!! 😂)
It was a really wonderful experience and in the end i was glad I was on my own. I didn't have any idea of how much the lunch would be but I was happy and able to pay for it - if another volunteer had been with me i probably would have felt stressed or guiltily for costing them so much money. The bill came to less than €50 including 2 wines, dessert and i ate like a lord. (in a similar restaurant in Dublin it would have been at least twice that)
Not an everyday dining experience but one I would recommend if you can afford it and are into food.
