NewGusto: A Home Cooked Meal While You Travel
We shared Foodhost back in August, a platform that brought local communities together to meet and eat amazing meals. NewGusto is a brand new network for foodies to connect with a similar concept. The site lets you meet new people, find a dinner party near by and probably enjoy an old-fashioned home-cooked meal (hopefully with grandma’s recipes).
