B’burg pizzas arriving at UES

Upper East Siders are getting a taste of trendsetting Billyburg.

Williamsburg Pizza — home of such menu items as tartufo with fresh mozzarella and apple bacon with smoked fresh mozzarella — is opening at 1615 Second Ave. at the corner of 84th Street.

The reverse migration of pizza chef Nino Coniglio’s signature slices and pies continues this summer, with a fourth location coming near Union Square, Side Dish has learned.

It may not feel like summer, but Manhattan mainstay Il Mulino is launching its seasonal East Hampton outpost this week.

The 3,500-square-foot restaurant of “Abruzzo-inspired” fare at 108 Wainscott Stone Rd., which seats 172 people, is slated to open Thursdays through Sundays starting this week — with seven-day-a-week service launching in May.

That’s when the restaurant will debut its 760-square-foot patio, which seats an additional 20 people.

Last summer, the East End outpost attracted celebrity diners such as Jimmy Fallon, who was so appreciative of nearby fellow diners who respected his privacy that he picked up the table’s $1,136 dinner tab, according to reports.

The Columbus Avenue Business Improvement District’s annual fundraiser, the Taste of the Upper West Side, will feature 16 restaurants participating for the first time, including Tom Valenti’s acclaimed Oxbow Tavern.

The May 17 event costs $115 per person, while the May 18 event costs $145 a ticket or $235 a person with a VIP reception.
