As someone whos done the endless shrimp multiple times, heres what I've learned.
you can get only 1 type if you like, I usually stick to the buttered first, you will burn out on that fast, ****loads of salt. Then move to the popcorn shrimp and feed until you feel sick. Take a 5 min breather and then keep eating.
if you dont feel suicidal when leaving you dun goofed
