Market Square

street.life! 400 will transform the heart of downtown Portsmouth into an al fresco dinner party, with tables lining the street and guests feasting on lobster, chicken, and corn all topped off with historically inspired Portsmouth orange cake and a complimentary prosecco toast. With a focus on commerce and community, the event continues the Chamber’s tradition of an annual dinner for our business community in an unusual outdoor setting. With the PNH400 partnership, the event has been expanded to invite all members of the Portsmouth community: Residents dining with their business neighbors.

In addition to the delicious food, the street.life! 400 dinner party will offer a concluding spectacle. This element of surprise will be served up alongside dessert. Throughout the evening there will be a cash bar serving local beer, wine and cocktails.
