It is not often stated, but Boston is a great walking city that has been made even greater by the creation of the Harborwalk and Greenway. If you have $50 to spend on one day in Boston and want to make the most of it, put on your walking shoes and start early. Begin your day on Newbury Street. Start near Massachusetts Avenue and make your way to Arlington Street. Window shop as you pass the fancy stores, and people watch as all the beautiful people exit the salons and spas that sprinkle each block. Stop for a coffee and a snack at L’Aroma Cafe, but get it to go. Wander into the Public Garden, rest your feet near the Swan Boats and sip away as they float by. When you are ready, stroll into the Boston Common, cutting through to check out the State House, from the outside. From there, head to Faneuil Hall for a free show; street performers are always on hand to provide entertainment. By now, lunchtime has arrived, and you are in the perfect spot to enjoy it. Avoid the high prices and tourist traps inside Faneuil Hall by entering the Greenway and choosing from the various Food Trucks parked along its path. Cross the Greenway and stop outside the New England Aquarium. The Harbor Seals entertain as well as any marine life available inside, and at no cost you should have plenty of that $50 left to enjoy amazing local seafood at Neptune Oyster. When you are ready for dinner, walk along the water to the North End, then meander along the tiny streets as you make your way to Salem Street, home of Neptune Oyster, and the BEST Lobster Roll I have ever had. It’s not cheap, but it is huge. If you are with a friend, share it (hot or cold, you cannot go wrong); I always order the hot roll: overflowing with sweet succulent meat, lightly dressed in melted butter and served on a roll. If you are sharing it, you will have money to wash it down with a frosty beer. The best part is that you are getting the a bite of a New England lobster without the cracking and splatting of dissecting one whole. Just be prepared to wait. This tiny treasure does not take reservations. If you still have cash in your wallet, and are craving dessert, make your final stop at Modern Pastry for a sweet Italian treat, one of the more famous bakeries in the north End, your reward will be worth the time you spend in the long line. Then hop on the T and call it a day.
