For me, this is the kind of place to which you just go to fill your stomach but you cannot really expect any culinary experience. The menu is very typical and so are the meals. Sometimes, the food is ok and sometimes it’s slightly below average. The staff is not very polite and what I absolutely hate is their restrooms. The only nice thing about Helios is its location in the middle of the park. In summer, it is great to be sitting outside and enjoying the calm and relaxed atmosphere of the park. If you want to enjoy the nature, then this is a good place. Otherwise, I believe there are much better choices in the area.
