Best roast lamb in Burgos
Casa Ojega is an institution in Burgos and it's widely thought to have the best "lechazo" (oven-roasted lamb) in the city. The restaurant originally opened in 1912 and has been serving up hearty Castillian cuisine like roast lamb, cocido (a garbanzo stew popular in inland Spain), ox tail, and Burgos' own morcilla blood sausage ever since.
The downstairs part of the restaurant is a sprawling tapas bar where you can stop by to grab a glass of wine and a quick appetizer, but if you're interested in trying the lamb (which you should be), make sure to call a few days ahead of time and reserve a table in the historic upstairs dining room.
