Probably depends on the type of fish and how fresh it is. Some fish smell pretty bad and I would not eat it while others... I feel like I am at a buffet and dont want to stop eating.
As for the taco shell, the ones that crack as soon as you bit into them make a real mess. Soft tacos are a nice alternative. Either one will get softer the moister it gets making eating a pleasure.
I hope this helps any unanswered questions:-d~
Hmmm, maybe it will make you think of more!
