The most gourmet bokatas can be tasted in San Sebastian during the week of Keler Bokata Astea, when over 30 establishments offer delicious and original bokatas accompanied by a Keler beer at a single price of 7 euros.  Bokata is a Spanish sub sandwich with various fillings.  It is, probably, one of the most popular snacks in Spain. During this special week, bars of San Sebastian add a gourmet touch to this simple but satisfying dish.  For example, "Spring" (a salmon bokata with arugula, cream cheese, avocado and Maldon salt) and "Japan Fusion" (a marinated turkey bokata with escarole, tomato, Gorgonzola cheese sauce, shiitake and wakame seaweed) are just few bokatas that stood out for us this year.
