Fantastic Grilled Sandwiches.
Birley's makes the best sandwiches. My favorite is the grilled vegie with goat cheese. I make this a stop each time I am around the Embarcadero! It is very casual. They do have some seating, but I reccomend getting your food to go and dining outdoors in the park right outside their door.
Best Sandwich in town.
This is one of my favorite casual dining spots in town. If you want to have gourmet sandwich, this is the place you need to try..... All the sandwich there are delicious and a lot of selections. I love the curry chicken salad sandwich the most. You just don't know how they can make such a good balance between spicy and sweet. Tasty and fresh.
Wow -- very hard to pick a sandwich because the range of possibilities is enormous. If you're doing low-carb the salads are amazing too but I couldn't pass up the great bread. Obviously the person designing these sandwiches is a chef -- you are eating ingredients the average deli guy won't even think of -- using olive oils, sauces, fruits&veggies to make a sandwich most delicious.
