We ordered a chicken burger and cheese burger for home delivery and were happy to find out that they delivered. Unfortunately the meat of the cheese burger was spoiled. But when we called to tell them, they were very apologetic and offered to bring another. By that point I didn't want to risk it with another burger, so they offered any other sandwich on the menu, the next day, for free including free delivery. The chicken burger was delicious, by the way, and even though I still haven't been able to find a good burger in Budapest, I was pleased with the service at Sunny.
