Yes, they are liable since it was a foreign object that could not be expected to be part of the dish served to you [a hard corn kernel might be part of a creamed corn dish for which they might not be liable]. There is no set time for an insurance company to respond, but a month without any contact is too much. Contact them again and point out if you do not hear from them within 5 business days you will assume they are denying liability even though it is clear and you will take the next necessary steps to obtain compensation.
