Handsome 19th-century brick buildings line the streets of the Old Port, with Portland's most enticing shops, pubs and restaurants located within this five-square-block district. By night, flickering gas lanterns add to the atmosphere. What to do here? Eat some wicked fresh seafood, down a local microbrew, buy a nautical-themed T-shirt from an up-and-coming designer or peruse the many tiny local art galleries. Don't forget to wander the authentically stinky wharfs, ducking into a fishmongers to order some lobsters to ship home.
