I'd say the second. One could argue that "Cheese Fries" is a collective noun allowing the use of a singular verb, but I would expect it to follow the same conventions as the noun on which it is based, "Fries", which is clearly plural. Therefore a plural verb should be used by the principle of Subject-Verb Agreement. I feel like I'm about to get trolled. Am I getting trolled?
and realistically speaking, regardless of which you say, only ******** will really care edit- i accidentally deleted my post except the last line, oops the basic gist was that they have separate meanings, the 'is' one meaning that the item is back as an orderable feature of the menu, the 'are' one meaning that you have fries on your menu again
The only circumstance in which #1 would be correct is if "Cheese Fries" referred to an item which was actually singular in nature. If someone made a movie called Cheese Fries, for example. Since you're saying they're on a menu, I don't believe that would realistically be the case in this instance.
but it is singular in nature, and here's why- when you tell someone what you're ordering at a fast food place (i imagine), you probably give numbers for how many of each item you want. if you say you want 3 cheese fries, that doesn't mean you want 3 fried potato shavings with melted cheese *total*, it means you want 3 orders the item being on the menu is the order, and when you discuss it it should thusly be in reference to the singular order of cheese fries (which are hopefully plural if you're counting them, but the order itself is singular)
I'm with Dagda here. If "cheese fries" is the name of the dish, then cheese fries is back on the menu or If "cheese fires" is used as a description, then cheese fries are back on the menu
The menu item is called 'cheese fries' not 'cheese fry'. A menu item is singular. And 'cheese fries' is ordered singularly not in multiples. You could say 'I'll have a burger and a cheese fries', short form of 'an order of cheese fries'. People do say 'I'll have a burger and cheese fries' but I would argue they are not ordering specific menu items by name but rather just describing the food they want. If they say 'burgers are back on the menu', this is also correct because they are probably referring to more than one burger item. Now if they refer to a single item 'the Big Burger' then they would say 'is back on the menu'. So the only way for 'cheese fries are back on the menu' to be correct would be if they offered more than one kind of cheese fries.
According to the Cambridge Dictionary of English Grammar (descriptivist) nouns which naturally describe groups can take either a singular or a plural verb form and still be grammatically appropriate. I think the second sounds better.
kaasfrietjes is terug op het menu (wrong) kaasfrietjes zijn terug op het menu (correct) alternatively : Kaasfriet is terug op het menu (correct) friet is also plural, but I doubt fry is in english. your second one is correct.
The first one is actually correct, since the subject is a singular item (you do not order multiple individual fries). In conversational English, either would be acceptable. Since the goal of conversation is clear flow of information and ideas (as opposed to correct grammar), the 2nd could even be a better choice. On an English exam, definitely go with the first.
