I don't usually do this, but I'm going to recommend a restaurant I've never eaten at. It looks THAT good! They specialize in - grilled cheese!
Pictured here is the Moscone -- fresh mozzarella, fontina, roasted tomatoes, basil-lavender pesto, kalamata olive tapenade -- the sandwich I'd try first.
Of course, this is not a lunch that fits in well with my weight loss plan, so if you make it there before I, do let me know.
