The two shopping centres are OK but have little that you cannot find in any town centre. Nearby towns like Reading, Watford and Uxbridge offer far better shopping.
The 35 minute train journey is achievable if you pick the one with just 2 stops. Many of the trains take closer to 50 minutes but at least it is better than fighting your way through the A40 Western Avenue carnage in the car.
There is NOT a bowling alley or an "out of town" shopping centre. The new town centre development has been waiting for over 3 years due to problems re-locating the big supermarket.
Hughenden Park is very pleasant (1 mile from the town centre) but the "waterfalls" have a drop of approximately 20 inches and the church and manner house are reached via a cattle field.
Town centre nightlife has improved dramatically over recent years and I have succesfully avoided the hooligan element but, like all towns, it certainly does exist. There is, however, a distinct lack of variety in restaurants.
The "multi-cultural" society includes a higher than average concentration of afro-caribbean residents in the area called Micklefield and there are the Asian populated areas of Desborough and Castlefield. That is not a criticism or a racial slur but do not expect blacks, whites and Asians living together in surburban bliss.
Property prices (and parking charges) are high but unemployment is low. The surrounding countryside is home to some even more expensive villages with a good selection of country pubs.
