Visited friends there this weekend.
Not much love given to Northern NJ here at Chowhound, but this town has some great food stuff going on, so here's a quick summary.
In addition to a bazillion good farm stands, there is a funky Pennsylania Dutch (mennonite?) indoor market outside of town on route 27 with of course great pretzels as well as dairy products, baked goods, meats, etc. Not cheap but good quality stuff (ie fresh churned butter at $5 a pound). Some of it is the repackaged stuff that I don't really get (why are they selling wasabi peas, exactly?), but it isn't tough to sort through.
The pizza place right in the center of Hopewell, Franco's, has great pizza. Crust, sauce and cheese all hit the mark. 3 styles -- regular, Sicilian and "tomato pie" which, as far as I can tell, means more cheese and less sauce. My friend also swears by their fries and cheese steaks.
There's a celtic coffee house, Failte, with lots of personality and good coffee. Almost next door is Brothers Moon, the local "nice" restaurant, with amazing desserts and great service, interesting food and lovely atmosphere. Haven't been to the other place further down the road, The Blue Bottle, I think, but word is pretty good. And to the left of that is the Hopewell Tavern and a bistro attached to it which serves Hungarian food, much to my surprise as this isn't very obvious from the outside. I had some great spaetzel and goulash there and it is really fun to look at their dessert display with mile high versions of just about every dessert you can think of including "euro" specialities.
Anyhow, didn't want any other visitors to the area to think there just wasn't much going on there. It is a really lovely little town with very worthwhile chow -- a pleasant town to check out and have a meal or two while poking around the area.
