Is it really worth the drive out there? I have only been to the Bass Pro (well, that always makes the drive worth it I guess) but I have never been to any of the other stores.
I like a few miles from Katy Mills and drop by there every couple months.
I think it is technically an Outlet Mall, but they do have a lot of "real mall" stores.
Bass Pro Shop and Sun & Ski Sports are the standouts for me.
My wife really likes the new Coach outlet store. They were handing out coupons (I think 20% off) for a couple weeks right after they opened. The purses are new, first run (not factory seconds) and typically much cheaper than you'd pay elsewhere.
I would recommend staying away from the food court though. I've never had good experiences with the food there.
Bass Pro is a good place to browse, I would suggest finding what you like and then buying online. Their prices are astronomical, which is why they are always expanding and adding to their store.
