Hi, ------- Yes they can, provided that they can proove that what you wrote was untrue. If you wrote that you didn't like the food and it was disgustting they can do nothing (cause that is your taste) but if you wrote that the place is dirty, there is not enough parking place, the music is too loud, and there were only 2 people at the most busy time (facts that they can proove are not true) than yes they can sue you. ------ Best regards,
