The premise is a restaurant sign featuring a cartoon of an animal that the restaurant serves in some form, often in ways that suggest it is cooking and/or eating its own species, or loves the idea that it is about to become someone else's dinner. My examples so far:
Little Q Hotpot in Arlington, and sibling Q Restaurant in Chinatown. Adorable lil' cartoon lamb in a bowtie.
Xinh Xinh, Chinatown. Exterior pho sign features a cartoon cow licking its chops.
Hot Pot Buffet, Chinatown. Cartoon cow licking its chops and giving the thumbs-up sign with a white-gloved "hand".
Pollo Doreño, East Boston. Cartoon rooster in a Stetson and neck bandana, holding a fried chicken leg with a big bite taken out of it.
Red-Eyed Pig (BBQ), W. Roxbury. Demonic pig.
Strip-T's. Maybe doesn't quite belong, as its logo is an anthropomorphic dancing strip steak on a bun.
Sweet Cheeks Q. Also a stretch, an abstraction: the tail of the letter Q is a curly pig's tail.
I like the food at all of these (but can't speak for the Salvadoran fried chicken joint, which I have yet to try).
I expected more of our local BBQ joints to do something along these lines, but many of the usual suspects don't. Redbones has a cartoon pig (in a suit, fedora and shades), but it's not on the signage.
Anyone seen a cartoon lobster in a lobster bib? A chicken about to tuck into some eggs? Any others?
