I don't believe they serve custard it's ice cream and they have tons of different flavors available. They have vanilla or chocolate as a base but you can add things like strawberries, Oreos chocolate chips, peach or pineapple.
It is an LTO or a Sonic limited time offer. We have it rolling on the display screen and in Drive Thru we have signage. Press the red button when you pull into a stall. Text deals to 876642
How do I order the BLT that's being advertised if You dont sjow it on the menu?
There were only 4 choices. We had these two: Strawberry M&M, Chocolate Oreo
