The lower limit games at the Grand are some of the worst I've ever seen. That goes for SD, DD, and shoe games. It's almost impossible for the lower capitalized player to profit at all. With the low limit shoe games they only allow mid-shoe entry with a bet of $100 or greater. Conditions are better in the high stakes rooms, but minimums start at $50.
Your best bet is Fitzgerald's. They have DD and shoes games with $5 minimums and SD with $10 minimums. Next I would try Horseshoe or Gold Strike.
Good Luck
