If you're curious about venturing out of the city, as far as mp's are concerned, Jersey has a few select spots depending on what your preferences are. Some of which get reviewed here pretty regularly in areas close to the likes of Dover, Passaic, an amp in Ridgefield(which ironically has a few girls that migrated over from NY), and Bridgewater. Jersey City has a cple, but the quality & consistency is no where what it was like yrs ago. For many of these areas, the services rendered may not always reach the same experience level as many of the spots in the city, particularly the Asian gfe spots like PH and others...so ymwv(your mileage WILL vary). The pricing will reflect that as well. Also, you spend a good amount of time driving to those locations compared to a short hop on the Metro.
If you did decide to come over, you're probably better off with the many Indy providers or agencies that do incalls out of 3-4 star hotels. There may be some screening involved, but you can definitely find gems that do compare favorably price & service-wise to those that provide in your neck of the woods.
