This Tuesday, Brunswick will welcome Flipside, a new, by-the-slice pizza restaurant at 111 Maine Street.

Before its official opening, Flipside will host an open house today from 3 p.m. to 6 p.m., allowing Brunswick residents to sample free slices of pizza.

"We call this farm to table pizza," said Bob Haggerty, Flipside's chef and manager.

The ingredients will all come from local sources, including pepperoni from locally-raised livestock and tomato sauce from organic tomatoes.

Flipside's co-owners, twin sisters Eloise Humphrey and Daphne Comaskey, and Comaskey's husband, Paul Comaskey, chose to open a pizza place because of the size of the property, which was formerly occupied by 111 Maine Café. The space borders Richard's, a German-American restaurant, and is also near Joshua's Tavern.

"We used to live in California and New York, and we wanted to make food we missed," said Humphrey. "Plus, we knew Bob, and he makes amazing pizza." Flipside's owners own El Camino, a Mexican restaurant in Brunswick that also uses local organic ingredients.

"We're going to play with the hours," said Haggerty. Initially, Flipside will be open Tuesdays through Thursdays from 11 a.m. to 9 p.m. and Fridays and Saturdays from 11 a.m. to 11 p.m. It will be closed Sundays and Mondays.

Flipside will serve basic pizzas, as well as specialty types.

The slices are "generously sized" and will be ready for takeout. Delivery service, however, will not be available.
