An interesting historical anecdote, but LONG obsolete...
We went to one of the Legal Seafood restaurants. I remember going to one with friends a lot when I was in high school, 25ish years ago. It was the local type of place that had newspaper on the table under the fried seafood. I think they tried to make them upscale. No one in my family liked the food, and my DH and DS love all types of seafood. I thought it was really overpriced. Big disappointment! I don't know if it was the one we went to, or all of them now.
It sounds as though you may have actually gone to the original Legal Seafoods all those many moons ago, which was back then actually located in the adjoining city of Cambridge (...not in Boston itself).
In the several decades which have gone by since then, Legal Seafoods CEO Roger Berkowitz has made his (now huge) company the hands-down
gold standard for quality monitoring and control in the entire Boston area seafood industry. Legal now even (entirely voluntarily) has its' own lab facilities to test seafood products before those products go out to their restaurants, including laboratory testing of all shellfish.
I'm not a fan of Legal's CEO Roger Berkowitz, who I have met personally on numerous occasions, invariably finding him to be arrogant and pompous. Just the same, the above quoted observations of long ago "yesteryear" are old news, neither relevant nor applicable today. You simply can't
get better quality seafood in Boston than that which is provided by Legal Seafoods' restaurants, although their menu is not inexpensive.
P.S. To be very clear, I have no
affiliation with Legal Seafoods' company; I have had numerous direct work related contacts with their operations over the past two decades but, now retired, I no longer have any direct contact with Legal Seafoods and I have absolutely no
reason to "wave their flag".
