The best I've ever had and ones that I've been eating for about 15 years now are at the Terrace Diner
585 Sunrise Hwy, West Babylon, NY 11704
Regular fries w/ Mozzarella and Brown Gravy, don't get the waffle fries. You can also order with Turkey gravy (yellow) or tomato sauce. Both are good but the ones w/ brown gravy are the best. This and a soup or salad (see below for reccomendations) is usually more than enough for dinner.
If anyone has any places with good fries and gravy please post.
The gravy is delicious so the hot open roast beef sandwich is really good, usually made with nice rare roast beef. One word of warning, stay away from mashed potatoes they're instant. Get fries and ask for extra gravy.
Another good choice is the Roumanian steak. It comes topped with onion rings. I usually like my meat medium rare, but always order this medium because it seems to taste a little better that way.
Creamed spinach is good for the veggie, anything else and you'll most likely be dissappointed. Usually comes w/ soup or salad, if it's Friday and you want soup, the Lobster Bisque is really good, not much lobster in it, but very thick. Matzo ball soup is decent.
They're famous in West Babylon for their Greek Salad which you can choose as your salad. The regular greek salad on the menu comes w/ stuffed grape leaves. It's probably not like any greek salad you ever had. The dressing is this homemade thick yellow honey mustard thing. It's hard to describe but people go there just to get containers of that to go. I think it has raw eggs, which doesn't bother me, but some might have reasons to be careful of that. By the way, if you decide to order the large greek salad platter bring about 3 friends to help you eat it; it's huge.
For a drink you might want to try a choclate egg cream, which will never be confused for a true egg cream but about as good as you'll find in this part of Long Island. They also make a very thick choclate milkshake.
The make really good tuna salad chock full of celery.
Try the Tuna Jackets with Cheese. They're potato skins filled with tuna salad and you're choice of cheese. I usually go with american, but an out of state friend once ordered them with mozzerella and said they were good. Also the traditional potato skins with american cheese, big pieces of bacon, and a side of sour cream blow away anything you could ever get at your typical Friday's type place.
The tuna sandwiches are made w/ two giant scoops of tuna, so ask for less if you want to eat it as a sandwich and ask them to toast your bread.
Their "tuna melt" is normally served on a crossaint. The open face tuna sandwhich is more like the traditional tuna melt, but they don't toast the bread unless you ask. Make sure you specify exactly what you want if ordering a tuna sandwich, i.e. "tuna on toasted rye, with melted american cheese." Sometimes they have new waitresses who don't know that there's three kinds of tuna sandwiches on the menu.
Most of the typical diner fare is good here (burgers, turkey club, greek pizza etc.) but the choices above are your best bet. The greek style food is not bad, but they use those fake preformed gyros so avoid those. Souvlaki is not bad, avoid the fancy greek dishes. I'm a sucker for the giant choclate chip cookies, though they're probably made from Pillsbury dough.
The red sauce is tasty on the fries or pizza burger but don't order any Italian style dishes on the menu. The pasta is always overcooked to a soggy mess (think canned chicken noodles). Also, if you happen to be foolish enough to disregard the advice on the Italian dishes, do not under any circumstances, no matter what the waitress tells you, get the Eggplant Parmigiana.
Let me know if you decide to check it out.
