The following is the e-mail response from Legal Sea Foods when asked which of their menu items are vegan:
Thank you for writing. Only our Vegetarian Box is Vegan friendly.
Are the sides such as steamed broccoli or rice vegan?
I’m sure our management team, once notified, can prepare a nice meal for you when you dine at any of our locations. We are very sensitive to Guests who have dietary restrictions. Please know, however, that many steamed items are steamed over an area where shellfish is steamed. It will be necessary for you to interact with a member of our management team when you dine with us.
If I knew when you planned to dine with us and at which location, I would make sure that your visit is facilitated properly. Let me know.
We hope to serve you soon.
