They need an apostrophe

interesting replay. thank
the photo makes me think of a movie that I loved, Easy Ryder, beautiful music, fine photo, bravo

You're probably right about their intent... but... if you want to get technical you'd look at it with the term "restaurant" included which would be the noun which is the object of a sentence, making the term "yesterdays" the/a modifier, in this case implying possession - which of course would need an apostrophe. If it were remembering the past, it would be something like "restaurant of yesterdays"

ummmmm... yes

Well... at least they advertise Vivaldi, Bach, and Tchikovsky

Yummy! Can we stop in for some penguin burgers?

This picture made ​​me think that I read Tortilla Flat, the great Steibeck, book now for the time of general economic depression

Looks like a really interesting place

Is that an "old miner" in the doorway?
