Grater Grilled Cheese in Chula Vista's Eastlake district brings a gourmet grilled-cheese concept to Birch Road in the Millenia complex south of Otay Ranch Town Center, building every sandwich on a proprietary five-cheese blend melted onto artisan sourdough bread. The SoCal-based chain runs additional locations in San Diego and Irvine, but this Chula Vista outpost pairs its sandwich lineup with the local craft-beer scene anchored by Chula Vista Brewery in the South Bay. Beyond the signature Grater 5 grilled cheese, the menu extends to 100% Angus beef smash burgers, butter-fried lobster melts, Nashville hot chicken sandwiches, and applewood-smoked pork belly burnt ends on the same sourdough platform. Pommes frites, tomato soup, and lobster mac and cheese fill out the sides menu, building a sandwich-and-soup program more substantial than the sub-style builds at Tlaloc Deli elsewhere in Chula Vista. The Cordon Bleu grilled cheese layers chicken tenders, French ham, gorgonzola, and roasted garlic aioli inside the five-cheese sourdough melt, running the griddle at 350 °F for a four-minute press.
