I hate romaine lettuce. I don't like the firm ribs down their center.
I like it better than iceberg and it is supposed to be better for you .
Romaine is widely available in North American supermarkets, but I always choose icerberg instead.
I like the shape of the leaves, it's like a taco shell or boat and great for low carb diets
I've found romaine has a fine-bitter herb taste. THis is due to the milky fluid on the outer leaves.
Did you have to say milky fluid. I don't think milk and lettuce go together. 
Haha. Romaine is actually the usual lettuce used in a Caesar salad.
