During the summer season (usually starting from July till September) Orfeas Athletic Club organizes Bingo nights (every Monday at 21:00). The event is held outside, so you can easily bring your dog with you (especially if s/he is your lucky charm!). There are plenty of tables to sit – some are inside the park where the restaurant is and the rest are outside on the street and pavement (we usually choose the latter not to bother Buddy with food smells).
Even if you do not win anything (the winnings vary from €20 to €2.000), it is definitely an entertaining and relaxing way to enjoy your Monday evening on a hot summer day. Your dog might not have as much fun, but still won't be as bored as waiting for you at home.
Make sure your dog is OK with the cats as there are many wandering around.
