A team including the owners of the acclaimed Wayside Tavern aim to launch a neighborhood bar on Spring Street in Portland this September.

Wayside owners Siobhán and Michael Sindoni have partnered with Chef Rian Wyllie to open Gill’s Bar at 133 Spring St. Wyllie was formerly chef and co-founder at Lenora.

The venue is named after Gill’s Handy Store, a bodega-style market that occupied the same space in the mid-20th century. Most recently, it had hosted Bao Bao Dumpling House.

“When we checked out that space, it just ticked off a lot of the things we were looking for,” Siobhán Sindoni said of the Spring Street location they’ve leased. “We really love being in the West End, and it’s still in that neighborhood but kind of in a different part of it, so we jumped on it.”

Sindoni said the concept for Gill’s is “a typical neighborhood bar, nothing too flashy.” The bar program will be cocktail-focused, whereas Wayside is more wine-driven.

“We like to start with really good classic cocktails and make them well and consistently across the board,” Sindoni said. The bar will also feature local and European beers and about 10 wines by the glass. Sindoni said the wine list will emphasize value, topping out at about $14-$15 a glass.

Wyllie’s food menu will include “elevated bar food classics,” she said, like a patty melt, an Italian sandwich, salads and stuffed clams. Former Wayside Tavern staffer Lynn Stout is Gill’s general manager.

The Spring Street space seats about 45 customers with a mix of high-top tables and booths, along with up to nine seats at the bar. The interior has new flooring, a new seating configuration and fresh decor, she said: “It’ll feel like a different space than Bao Bao.”

Sindoni expects Gill’s Bar will be open Thursday through Monday, starting at 4 p.m. She said they may eventually add daytime hours on Saturday and Sunday.
