It really depends on your party. If it includs children, then definitely try Garden Grill! Characters, fun, and foods they will recognize.
I have not eaten at Spice Road yet, but have an ADR for our Nov. trip, so I have looked over the menu thoroughly. Like you, we would like to try some new restaurants during this trip.However, we are a party of two adults. I am not sure how a child would like it.
