AMAZING SANDWICHES !!  Earl's lived up to it's reputation.  I love their hot sandwiches and how cheap they are ($6.99) especially since it's on the strip (in Planet Hollywood).  Earl's is also 24/7 now, and be sure to try their brownie sandwiches if you've got a sweet tooth; my boyfriend made us walk to Earl's THREE TIMES for these brownie sandwiches.  All in all, a must try when you're in Vegas.
