20 Feet has been a great place to get a lobster roll since it opened in 2013, but the recent addition of a covered patio complete with climate control makes this East Dallas seafood shack a great place to pass some time. The restaurant is BYOB, which can save you some money, and the staff is quick to supply a bucket of ice for whatever bottled vice you show up with. Add some fried clams, a few dozen freshly shucked oysters and end the evening with a slice of Key lime pie, and you've got the makings of a mini beach-side vacation without the four-hour drive.
