My husband and I eat there quite often and have found the service to be very friendly, with the food arriving quickly. We have never found the owner to be anything but friendly and mild mannered. Perhaps the people who indicated the owner was rude had the wrong restaurant in mind. We've arrived there with a group before and not everyone was there at the same time. We were seated and offered beverages while we waited.
Restroom is always clean. Food is decent, reasonably priced. The soup is great. It's our go-to place when we decide to stop after work or while running errands.
