Since I don’t drive a car, I like to do my long-distance travelling by train, even though the weather in Finland or some other random conditions make them not as reliable as buses, and despite the fact that these days they can be quite expensive if you don’t buy your tickets well in advance. Whenever I head to Helsinki, Turku or even way up north, to Rovaniemi, by train, I like to pick my take-away filled baguette from the small Hella ja Huone deli-café just inside the railway station near the other entrance to the city & to the tracks.
There are often three choices of the day, one of which is vegetarian. I find their baguettes very tasty and I appreciate that they are made on the spot with fresh ingredients. For me, a half-size baguette is big enough. If you have time to sit down, they also offer great cappuccino or other hot & cold drinks (and something sweet) to go along it. If you get a salad, you can choose what ingredients you want to include in it.
Even if you are not travelling anywhere, Hella ja Huone (“stove and a room”) deli is a good place to sit down and refresh yourself while the people around you are hurrying to get their trains or their bus rides back home.
