We waited 50 minutes for a to-go order. It was chilly out so we wanted a chance at our food being warm. The ready part of the order sat on a counter getting cold. Cold chicken sandwich, cold fries and cold clam fritters. The staff didn’t seem to have any adult guidance. I’ve been going for years and will now be looking for a new place. For the record the OMG lobster roll was warm at best all claw meat and tossed in upside down.

Food was good overall. Clam cakes(fritters) were unfortunately over-cooked, but still decent. One extra star for the view!
