Budapest - In the open air

One of the things I love about Europe are restaurants with outdoor seating. We of course have that in the states, but it's not very prevalent. I'm not really sure what I find so appealing about it. Is it a sense of community? A sense of openness?In this spot, along the Danube, with rows of tables, covered in clean, crisp white table clothes, I just wanted to sit and take in the environment. Perhaps it's just simply inviting.Regardless, it makes me feel welcome!
