They didn’t have custard where I am from. This stuff is like eating a fluffy cup of heaven. After you try custard it really is difficult to go back to ice cream. «Concrete» is the term the menu uses for basically a mixture of the custard and any of the toppings you want. My fave is the vanilla concrete with peanut butter and brownies which is just a slightly altered version of the«Driller». I am happy they offer a mini 10 oz portion size. For something a little different, my boyfriend recommends the vanilla concrete with raspberries and cookie dough.
