ugh, I like the concept, but I hate those tablet things at Chili's. Completely useless, tried to order desert using it, and it said we couldn't cause the waiter had closed the table or something already. Waiter took about 10~15 minutes to even stop by the table again. End result: We picked up desert on the way home and left a lousy tip. I can see it for McDonalds, as they are fast food, but if you are a sit-down restaurant and don't have enough employees to actually serve your customers, dinky android tablets are not the answer.
