Resident Foodies says: Who has the best grilled cheese sandwich in San Francisco? It might be The American Grilled Cheese Kitchen on 1 South Park Ave. (cross 2nd St.). We tried out the all cheese Mousetrap, which consists of Tillamook sharp cheddar, creamy havarti, monterey jack, on artisan sourdough, for $ 6.00. See above for a photo (we split it 6 ways–it doesn’t normally come like that). Many of the other sandwiches on the menu are a bit more exotic, but we wanted ours more basic–you know, the classic grilled cheese sandwich. The Mousetrap was, indeed, a warm, comforting sandwich, but we are still undecided whether this is really the best grilled cheese in town. One thing is: we would like to try this on different breads. The American Grilled Cheese Kitchen uses artisan sourdough bread on the Mousetrap. We wonder if a different kind of bread would produce more of a classic grill flavor and texture. The sourdough gives it a SF feel, but it may not be the best bread for grilled cheese.
