Red Robin is a magical place--it has a bar in the middle, but it's still a good place for families to eat together!
If you sit at the bar, you don't have to wait for a table, and you can still order a meal. the bar is wide enough that this isn't akward at all.
There is a small arcade towards the front of the restaurant and the outside is exciting and looks great at night when it's all lit up.
There are tons of fabulous varieties of burgers available. The one that I tried was delicious and the others look very appealing, too.
