You gotta love a down to earth place like Sylvester's. 5 of stopped in for lunch, 5 different types of burgers and we all were happy. The onion rings were fantastic. Price was good, service great. I'm definitely going back.

This is by far the best hamburger place on the Central Coast. Old Fashion, juicy burgers and fries. Great milk shakes too. Lots of other things to choose from. Tight, but seating in and out.
