Been there just once, with a friend who highly recommended the place, and the visit was very satisfactory.
Despite being incredibly crowded during the lunch time (well, that's actually a good sign), order for three was served very quickly, and our soups were delicious. Huge portion, very well made.
Place itself is tiny and beaten, but not filthy - and it should be way more quiet and comfy outside of the rush hour.
Would definitely like to be back!
