My experience with Mesquite, TX took place in the form of a two week business stay in early 2009. My first impressions were good and they were further reinforced by friends who live in Mesquite.
I never expected too much going to the city of Mesquite, TX since I have always found cities in Texas to be very bland and almost desert like. My judgmental opinion may have got the best of me since Mesquite is truly a wonderful little city. I was greeted by friendly individuals, nice clean streets lined with green grass and more than enough options for restaurants, bars & shopping.
Friends who live in Mesquite have commented on the excellent school systems and strong community. I can't comment on the schools but the community appears to be very clean and friendly. There are plenty of shopping in Mesquite from a large mall down to novelty shops.
There are plenty of good dining opportunities from larger chains to small and delicious local restaurants. The nightlife was rather bland with mostly small, local bars. I heard talk of some bigger clubs but never came across a single one in Mesquite. I did notice an abundance of "hiring" signs which is definitely a good thing for residents in need of work!
