It isn't so much as great, as convenient. If you grab the crew car, exit the parking lot, go up to the main drag, take a right, go about 1/4 mile, take a left, go under the overpass - stay straight and you run into a little area where Jeveli's is. Feels like a mobster hangout actually. The lobster ravioli and baked stuffed haddock are really good. The veggies are horrible.
And when you are done there, a short one block walk to Spinneli's has an incredible bakery if you want to take some goods home. I buy cannolis and Napoleans there, put them in the nose of the jet next to the LOX orb to keep it cool (plus FL380 LOL..)..
