It's the original Sunset Grill location, and it lives up to that, as it is your traditional diner, which hasn't changed one iota since opening. It's quaint and fun, and hard not to love for that reason. Even though the breakfast isn't the best in town, it's exactly what you expect for a little greasy spoon. The value for dollar also isn't bad (with typical early bird specials being a real deal, and the "Lumberjack" being the best value for dollar of the standard breakfast fare, in my opinion). The staff has always been pleasant. They now take debit in addition to cash. Biggest gripe I have with all Sunset Grill locations: the style of their home fries (large chunks of potato that often have a mushy undercooked texture, but that's a personal preference thing).
If you're going to go to one breakfast/brunch spot in the Beach area, try this one, it's the authentic experience.
