Large parties looking to enjoy Black Cow's casual burger shack menu and memorable craft cocktails should request a table in the back room. The architecture of this former bank is sure to impress.

Visitors here Irish classics like Shepherd's Pie or bangers and colcannon with a pint of Guinness at this popular Old Port pub. While the bar fills up fast during Happy Hour and late night, the upstairs dining area offers plenty of room for large groups and even banquet functions.

Portland's original craft brewpub is a spacious Fore Street affair where the beer's made in-house, the menu is crowd-pleasing, and there are large, communal picnic tables.

This sizable Commercial Street fixture offers a variety of fresh seafood, perfect for out-of-town guests looking to get their fish fix. Insider tip: ask for the "lazy lobster," where the steamed lobster comes pre-picked with a side of butter. It provides the mandatory Maine lobster experience with none of the messiness or that silly bib.

Looking to watch the game with friends? Rivalries offers a standard sports bar menu (the Thai chili wings are standouts) and plenty of seating upstairs, including large booths. Multiple TVs ensure that everyone gets a good view of the game.

This spacious brewpub on the first floor of the Hampton Inn offers a brew and a dish for everyone. The draft beers range from summer seasonal Simmer Down, a low alcohol hop crusher, to dark, roasty Lake Trout Stout, and the menu features a range of solid dishes from burgers to shrimp quinoa bowls.

Slab's patio is the perfect place to bring a traveling band of merrymakers to enjoy hearty Sicilian fare and a refreshing drink, with live music most summer nights. The interior has some big booths, too. While baker Stephen Lanzalotta is best known for his pillowy Sicilian "hand slab" pizza slice, thin crust pies are also a winner, and big enough for an entire group.

The latest business to occupy this sprawling restaurant space on Commercial Street, Solo Italiano offers high-end Italian cuisine. Well-sectioned dining spaces create an intimate vibe while still allowing for large groups. Don't miss the chef's award-winning pesto.

This Mediterranean newcomer is one of the largest restaurants to open in Portland, with nearly 300 seats in its multiple dining rooms. The menu's small plate starters like hummus, warm olives, and falafel are especially good for sharing with a group.
