If you are staying at the Ramada and don't feel like going far for food there is a good value restaurant almost next door, just the far side of 8th Street. The Moonstar is one of those all-you-can-eat Sushi/Chinese restaurants that I am so fond of. I have written elsewhere about one in Rancho Cordova that Kevin and I frequent regularly. Moonstar, being slap in the middle of San Francisco, is bigger in every way.
Going in there, I was struck with the question of how I might feel if I were a refugee from somewhere in Africa recently arrived in the USA. The tables were positively groaning with food. There were serried ranks of Sashimi, huge basins of Chinese dishes, vast steamers full of dim sum, and mountains of oysters, mussels and prawns. And for one single down payment you could eat as much of this as you wanted. Just take a look at the photos and you will see what I mean. If ever there was an embodiment of the Land of Plenty, this is it.
What is more, the food was good. There's no way Kevin and I could have sampled everything, but we had no complaints about anything we tried. The only warning I would give is that you should try to go for lunch midweek. The weekend and evening price has around a 100% mark-up. I'm not sure whether the same massive array of food would be available at the midweek lunch price, but if you are on a budget the saving will make a big difference.
