We had supper at Grandma's Kitchen on a trip to Monterey Bay. We chose it because it was near our hotel. The food was excellent--Homestyle cooking. We'd chosen breakfast items which are served at any time and found them to be excellent. The service was efficient and very friendly and homey. The cost was quite reasonable. It was quiet, and not so busy as some of the places in the more touristy areas.
The decorations centered on owls, and was to me a little unnerving, creating a kind of strange atmosphere. If you're looking for something quaint with good food though, this is a good choice.
