Personally I like the Vacaville outlets much more. The off saks is the only store worth going to in Folsom, and maybe the kenneth cole.
There were some hugo boss ties I wanted to go back and get at the off saks, even though I think they were still like 75 bucks. I like penguin, and they have a lot of penguin stuff, but that is more casual. I need to go out there soon to return some penguin pants that shrunk, never buy panguin pants.
If you have 30% off though I'd definitely use it and check it out. The suits and ties are quite limited compared to the women's clothes though. Also, maybe check out the Vacaville outlets on the way. You can find a listing of stores on the web, I always frequent the Banana Republic outlet. Found a great madras summer blazer there for $30 last month on clearance.
But then again, ANYTHING is better than the not-so Great Mall. Thinking about that nasty random carpetting gives me the shivers.
