Review: We came here on a Saturday - trying to find the place was a challenge. It is located on the second floor, up a narrow staircase, and there is only one small sign above the doorway indicating the restaurant's name (most businesses on the same street were closed). Contrary to what the other posters found, on the weekend we had the option to pay by kilo, or chose an all-you-can-eat buffet for about 25 Reals. We did the open buffet, given that they had literally dozens of food choices, all of which were great. The selection was incredible. Tons of salads, "sushi" rolls, vegetables and tofu on a grill, mock meats, soups... you name it. Even a great vegan stroganoff. Juices were available for order, too. This place made for a great break while exploring the historic Centro. The place also sells a small selection of health foods. Credit cards are accepted.
