wrt Jamaican, Mexican, Italian and German food
only jamaican place i know is up in richardson, campbell & plano (at least there used to be one there).
wrt mexican or tex-mex or high end mexican, "they're everywhere!!!"
ditto for italian.
wrt german - Kubys (near SMU university), Black Forest Deli (off E. Northwest Hwy east of US 75 Central Expwy), and Bavarian Grill (Plano, n.w. corner of US 75 and Parker).
another great chocolate place is Chocolate Secrets - on Oak Lawn north of Blackburn. expensive but fan-yummy-tastic (almost mouth orgasms).
there are a few swingers clubs in dallas - Colettes and Velvet Curtain. you can def get it on w/ your date but iffy on getting it on w/ someone you meet there.
i just did a search for Velvet Curtainand found this from 3+ yrs ago.
