Review: I visited Gaia today for lunch (the hours listed here are accurate), and was very pleased by the location, cleanliness, decor, daily-changing menu, price, variety of dishes, informal mood, etc. I was also pleasantly surprised to find out that Gaia is a totally *vegan restaurant as well. (In Spanish, "vegan" is simply "vegano".) It seems that the food here is both made and served by the owners, who are very friendly. Some English is spoken here, so I would recommend it for non-locals as well. Tourists can easily find it, as it is only a few yards away from the front of the famous and centrally located Cathedral of Burgos. The restaurant was full when I was there, with people waiting outside. It has a warm atmosphere and about 8-10 tables for 2-4 people each. As I mentioned above, the menu changes daily, but here's what I had today as an example: The "menu del dia" was only 10 euros, and included an appetizer, 2 courses, bread, wine or bottled water, and dessert. For each course and dessert there were at least 4-5 options to choose from. My appetizer was a white gazpacho-like cold & creamy vegetable soup with crushed peanuts on top. Next was a hot plate of zucchini with vegan cheese and some tasty green garlic sauce. Last was seitan and mushroom ravioli with a creamy sauce. I also had a basket of whole wheat bread, organic red wine, and homemade vegan blueberry yogurt (so good!) for dessert. Everything was presented nicely and, most importantly, was delicious! I recommend Gaia to anyone and everyone who visits Burgos.
