No joke. Everyone I know who has ever had one of their sandwiches is in complete, 110% agreement; the non-descript Marios Italian Deli Market & Catering has the best sandwiches in the entire world. No exaggeration, no arguing. The absolute best.
Take a number. They start with an entire loaf of fresh baked Italian bread, and slice it lengthwise twice, and add layer after layer of imported Italian deli meats and cheeses ( or stuf it full with marinated mushrooms and vegetables for the vegetarian), with your choice of a special mustard blend. It's the generous amounts of the absolute finest ingredients available that make them so astoundingly exceptional.
In fact, every single person I know, except myself, has had only one type of sandwich there. Because once they've had that one -- whatever the variety -- when they go back, they just can't bear to pass that one flavor up.
It's that good. Oh, and there's one of the best imported food stores in California there too (what Treader Joes wishes it was like), so you can shop while you wait your turn, arguing with yourself over whether you can brting yourself to try the prosciutto whe that roast beef you had last time was sooooo good....
