The food was mediocre, and the service needs to improve.
To the server... You should come by and see if the food was correct. My order got screwed up, but there was no server around to let them know. If you want to increase your tips, then increase your ticket amount. We would have ordered dessert, but you never asked. You just ran by, dropped the check on our table, and didn't even ask how was the meal.
Do better next time.
