I've been tasked with planning a 65th birthday dinner in a couple of months for 12-15 people, including three kids under the age of 12. I'm out-of-state and not in touch with where to start looking. We will be congregating in Melville, but do not need to be limited to the area. Places where similar family gatherings have occurred are La Parma III and Mac's Steakhouse in Huntington Village. Not looking for anything overly formal, but price isn't a major consideration. Biggest criteria is we need to accommodate a disabled guest who has difficulty with mobility. Any recommendations are greatly appreciated.
