Sandwiches by the Sea is a classic little joint with good subs. It's tiny, and has a beachy vibe. It's a good place to get a nice sub that you can take to the beach for a picnic. The walk is short, so it would be no problem. Or if you can't wait, you can sit down on a bench right outside and watch the traffic go by. Prices are a little high for a sub, but the location's convenience makes it worthwhile, especially if you are limited in budget and transport mode.
