I've heard of and tried the place in Freehold on Rte 9, which was good once out of 2 times, and also on rte 130, below Hightstown more toward Hamilton, hidden at the back end of a small strip shopping center placed perpendicularly to the east side of 130. Once in a while they have jalapeno cream cheese. Good but very very hot in summer.
There's a bagel-ette on Quaker Bridge Rd in Hamilton at the shopping center at Youngs/Sloan, and the bagels are very good and they serve jalapeno cream cheese as a matter of course, but the place isn't quite clean. Same people taking money and skipping using gloves to prepare food etc.
But the best we've found, by far, is a bagel place on Rte 29, in the CVS shopping center just north of Lambertville, across from where David Rago's auction house is. Two wonderful Indonesian sisters just have to be Jewish in a former life, because they have the best chewiest (and yes they boil them) bagels with tons of stuff on them. They survive splitting and freezing very well, which is my preferred method of keeping them around. Go early; they run out. And best of all, for me, their everything bagels do not have caroway.
