You need to speak to them about group parties. I just comment about the food.
I highly doubt they give discounts for birthdays. Please call them directly as Michelle suggested.
There give a free dessert or free appetizer for one birthday person. You also have to show proof it is their birthday.
Not sure about discounts. I'd suggest calling them to find out. They seem nice, so they'll probably be willing to work with you on that.
