The North Dallas/Galleria area is a nice place to stay. There are a lot of places to eat/shop and downtown Dallas is just a 10 minute trip down the tollway.
Stay away from the 635/75 area though. It's known for LE and is very shady. Also, the construction that is going on there is a disaster course from hell (As is most of 635 right now).
+1 to BSB on Galleria! Don't forget Ft Worth either. Lots of horny gents on that side of the metroplex too! Which reminds me, I need to make a trip soon!
