I know the guy who runs it. He used to swim at the Red Bank Y. Ironically I think his name is Lou.
My impression is that he caters to a limited number of well off and slightly older regulars (read NYC money people) who kind of keep him afloat, especially during the summer. He owns the building , and the food there is not cheap, so a handful of good covers a night may be all he needs. He keeps talking about cashing in and moving to Florida, that location with the license has to be worth a couple mil.
And... as noted....they have a liquor license.
The food at Harry's is a little better than average for the Rumson/Sea Bright Area, but then there's not a lot of competition there. I'd say Anjelica's is a little better, What's Your Beef is a quaint tribute to yesteryear, and Salt Creek and Undici are way worse. And Bahrs just blows when it comes to lobster.
