Eric Trump

The Waverly Inn got an unexpected guest last night.

Sources spotted Donald Trump‘s son Eric with his wife at the West Village eatery, which is co-owned by Graydon Carter, editor in chief of Vanity Fair. (No word on how he liked the food).

Perhaps Eric was taking notes on The Waverly Inn’s menu for his father’s next Tweetstorm. His visit follows Vanity Fair’s scathing review of the Trump Tower’s Trump Grill titled: “Trump Grill Could Be the Worst Restaurant in America.”

That story, which was penned by Tina Nguyen, lambasted the restaurant’s food selection that included “flaccid gray Szechuan dumplings with their flaccid, gray innards.” The writer also took shots at the president-elect, who is characterized as “a poor person’s idea of a rich person.”

President-elect Trump took to Twitter — his favorite medium — on Thursday, writing: “Has anyone looked at the really poor numbers of @VanityFair Magazine. Way down, big trouble, dead! Graydon Carter, no talent, will be out!”

VF publisher and chief revenue officer Chris Mitchell cited the magazine’s strong web site traffic and rate base, and told his staff in an internal memo, which included a screen shot of Trump’s tweet: “I think this counts as a win. Dear Donald, the #s are quite good, actually! :).”

Since then, VF has unleashed a sort of social media campaign that mimicked Trump’s way of speaking, in the hope that people would subscribe.

“Vanity Fair: way up, big success, alive! Subscribe today!” VF said via Twitter and Instagram.

The battle between Carter and Trump has been brewing for some time. For those not in the know, Carter has been poking fun at Trump since his days running the satirical magazine Spy with Kurt Andersen.

Back then, Carter branded Trump a “short-fingered vulgarian.” More recently, the editor in chief of Vanity Fair took to the pages of his magazine where he penned several incisive editor’s letters on Trump. Following the election, Carter unleashed a blistering, lyrical critique of the election results, writing: “Only in America could a serial bankrupt pass himself off as a successful businessman. (And almost none of those he bankrupted were even regular businesses. They were casinos — where people essentially come to lose their money.)…Only in America could a man whose primary national exposure was appearing on a reality TV show become the reality that so much of the world feared. Do not tell me America is no longer a land of opportunity.”
