The service was fast enough if you ordered more than one item at a time. The good thing is the serving sizes are a lot smaller than a typical order from a restaurant, this way you can try more items on the menu. It's good to ask what it is that you are ordering to prevent any surprises when the food arrives. The down side to having a large group is that some orders might not make it to your table due to numerous orders being taken.( that's a given)
Over all I give this restaurant a 3 because the food tends to taste similar the more you have.
