I visited Dona Franca in May 2015 and had the set lunch deal for 20bs. It consisted of a a drink, bread and spicy salsa, vegetable soup, followed by a main course of lentil and beans with rice. There was no desert. The food here was served quickly and the service was friendly. I have to agree with some of the other reviewers and say that the food was quite bland and definitely could have used more flavour. We used to go to El Germen next door but this particular day they were not serving a vegan option so we went to Dona Franca. El Germen is definitely better and you get a desert. However, Prem, which has just opened up on Calle Grau #209 is better than both Dona Franca and El Germen.
Cons: Bland food, No desert incl in set menu
