I liked HOU but thats bc I have family there and so I went home after training most days but don't kid yourself, Hobby Airport (where the SIM is) is not the safest of places. I wouldn't walk outside the hotel parking lot after dark, I personally know of someone who was robbed outside of Flight Safety a couple years ago while he was waiting for the hotel van. Granted this was back in the day of paper charts so thats all those guys got away with but regardless I'd keep your head on a swivel. The SIM is the worst one we use but the instructors were fine. There's a BBQ place right next to the hotel called Central Texas BBQ which was fantastic and you get pretty great cookies from the front desk everyday. Definitely more food options at DFW but it was also nice to get a change of scenery after being in DFW for X amount of weeks for ground school.
