The portion sizes were huge, the food was cheap. We didn't have to queue too long and the restaurant had a good atmosphere and ambiance. We loved every little thing until the end.
We know first hand, having travelled around all of Cuba and been to many restaurants that there is no tax added onto food bills, nor is service. Instead in Havana some restaurants have started to copy the American/British style of adding service on automatically. By default they do 10%, this is normally clearly shown on the menus/receipt. At the end of the meal when we asked for the bill we noticed our waiter, only when alone, would tell diners that "service is not included", which could have been the truth. However, when our bill arrived the receipt showed "10%" at the bottom with no words next to it. Thankfully we knew this was the autoadded 10% service, however when we left our money the waiter said again service is not included, we pointed out the 10% at which point the waiter lied and said it was a tax. Don't be fooled, there is no tax, we confirmed this with the restaurant and our AirBnB host who lives in Cuba. Shame on the waiter and shame on the restaurant, this should be stamped out.
