in the raw

The OU Daily, local campus paper reviewed a new sushi restaurant in the area. They had the following to say:

A square sushi bar sits in the restaurants center like an island.

The omission of an apostrophe here changes the word from a possessive to a plural. Not acceptable.

From a style standpoint, I take issue with the article repeatedly referring to the restaurant as "in the raw," quotes included. Having not been to this particular restaurant, I cannot say whether the quotes are actually part of the name or not, but I would guess not. This theory seems to be discredited by their later use of the possessive as "in the raw's" - with the possessive inside the quotes. My impression is that they're there to distinguish the lower-case name from the rest of the text. Again, not acceptable. If the restaurant chooses to spell its name that way, it should be preserved that way. You don't see people writing about "McDonald's" or "Subway," for example.
