It's Logan. It's not like you have much choice. An extra star removed for not having much choice. Otherwise, there are pseudo-local breweries and fried food goo vendors available. After security. That is a mess, quite understandably.
If you head out to BOS's rental car area with your own GPS, you're likely to encounter directions like "take road north." When you're heading south, these are of no use. The various signs are marginally better than California signs. Good luck.
