Katie's of Smithtown on Route 25A is mostly know for being one of Long Island's "most haunted" bars, according to the pub's website. The eatery has been featured on the television series "Paranormal State" and the owners have posted a series of videos documenting what appear to be glasses flying off of shelves and other unexplained occurrences.

Teller's looks a lot like an old bank -- because it used to be one. The site was originally constructed in 1927 as the First National Bank of Islip before later becoming home to Chemical Bank. The Bohlsen Restaurant Group purchased the building in 1999 and established the steakhouse, but kept certain defining features like a wine cellar in an old bank vault.

Nearly 40 years ago, a post office in Babylon was transformed into a cafe filled with quirky antique decor. The restaurant, pictured here in 2009, is owned by the Lessings family, which also operates Library Cafe in Farmingdale. It retains many of the elements of its forebear, particularly its facade, which features Grecian columns and golden statues of bald eagles.

The Good Steer

The Good Steer has been serving customers in Lake Grove since February 1957, and continues to be owned and operated by the McCarroll family. According to the restaurant's website, The Good Steer started as an "upscale hamburger stand" fashioned with roll-down garage doors and was popular among local celebrities who were traveling to the Hamptons.

The Good Steer was renovated in 1965 as a sit-down restaurant with an emphasis on promoting a cozy country home atmosphere. It continues to be a popular stop along Middle Country Road, especially for visitors to the nearby Smith Haven Mall.

Tara Inn, located in Port Jefferson, was opened by local entrepreneur Joe Higgins in 1977 and has been family-run ever since. The family estimates the building to be around 100 years old and said there was a four lane bowling alley in the basement at one point. Several employees have even claimed to have seen the ghost of a woman walk across the basement kitchen.

Higgins named the pub after one of his daughters, who is a Port Jefferson village justice. The Irish pub is known for its old-fashioned menu that includes a $2 quarter-pounder burger and $10 lobster.

Gunther's Tap Room in Northport has a long history in the town dating back to the prohibition era, when it housed a speakeasy in the basement. Beatnick author Jack Kerouac was also known to frequent the bar in the '50's and '60s.

A fire broke out in Gunther's in May 2017, destroying the interior and damaging several apartments in the building. However, the current owners have pledged to rebuild the bar and restore as many features as possible, including the original bartop and taps.

As its name suggests, the building that currently serves as Library Cafe in Farmingdale originated as one of the village's two public library buildings until a new branch was opened on Merritts Road in 1994. The Lessings family purchased the building and opened a restaurant in 2000, and continues to serve an eclectic menu of American fare and literature-themed cocktails.

Roe Tavern

Roe Tavern, seen here in 1982, is famous on Long Island due to its connection to one of America's founding fathers. George Washington documented spending the night at the house of "Capt. Roe, which is tolerably decent with obliging people in it" during his visit to Long Island in April 1790, following the end of the Revolutionary War.

Roe was a tavern owner who also worked as a member of the famed Culper spy network, which supplied Washington with information about the British army during the American war for independence, according to Beverly Tyler, historian for the Three Village Historical Society. Although the home was moved in 1936, a historical marker for Roe Tavern stands at the intersection of 25A and Bayview Avenue in East Setauket.

Finnegan's Restaurant & Tap Room, with its tin ceiling and walls, has been a Huntington institution for more than 100 years. It was established in 1912 by Andrew Finnegan and has cycled through five owners since. For the past 16 years, it has been owned by the Lessings family.

During the prohibition era, the bar was a speak-easy, according to Tommy Forte, general manager of Finnegan's. There was a cigars/tobacco room, and alcohol was made in-house and served in tea cups. A secret code was required for entry. It was also a popular meeting spot for local dignitaries such as governors, mayors and town officials.

Finnegan's Restaurant and Taproom, seen here in 2012, is still a popular gathering spot for many locals, and has been nicknamed "the tears of Huntington."

The Jon Thomas Inne in Bay Shore was originally purchased in 1925 by ballroom dancing team Arthur and Josephine Miller, who used it as a summer resort, according to the restaurant's website. The Millers later converted the attic into sleeping quarters for construction workers and leased the house to Harry and Elsie Seifert in 1938, after which the sun porch was converted into a bar.

After exchanging hands several more times, John Hickey and Thomas Lally purchased the building in 1977 and renamed it The Jon Thomas Inne. Hickey and Lally retired in 2013 and sold the restaurant to the current owners later that year.

Hildebrandt's Restaurant in Williston Park opened in the 1920s as an ice cream parlor and candy shop and was named after the original owner, Henry Hildebrandt. Over the years, it has morphed into a '50s-style luncheonette.

The Valencia Tavern in Huntington was built as a residence in 1933 by Benjamin Juliano, but was rezoned as a business later that year so Juliano could serve food from his home. Recent plans to demolish the restaurant were stalled in January after the town planning and environmental department sent a letter of denial to the developer.

Even though the Babylon Carriage House restaurant was first established in 2003, the building itself is an actual carriage house dating back to just after the Civil War, according to the eatery's website.
