The eating out secret of Burgos is a small bar restaurant named Bar Pancho. On an atmospheric narrow street - lane really, just a couple of hundred yards from the cathedral - Calle San Lorenzo, 13-15.
Small place, long and narrow, eating area on the left behind a wooden screen and bar on the right. Family owned, friendly, cheerful, real fresh cooking at a great price - oh, and if you are American reading this, it is immaculately clean - and! the locals eat there!! Nuff said! Was there with a pal, was marvellous, and the staff gave us big hugs when we left! Mind you, we chatted to them (in appalling five word Spanish!), complimented the cook - she came out to see us, was so pleased we had done that.
Very good local house wine too!!!
Actually - I don't know if I should be posting this ... next time I'm there it will be packed with pilgrims and I will have to go and eat a stale bocadilla somewhere ... dang!
This is it -
