Its been 10 years since I was there, so most of the places have probably been closed down by the local health authority since then.
Whilst you're wandering along International drive, you should spot loads of free papers (in boxes a la the Superman films), they have loads of discount coupons in them......... and the savings are significant. One coupon we picked up was for a Chinese eat as much as you like buffet, it was pretty good so we made more than one trip and sat stuffing ourselves with crab on many a night.
Belz factory outlet is well worth a visit for discount clobber, watches etc.
