I've eaten there (in one meal) with a carnivore who thinks vegetables should be banned, a vegetarian (the two are brothers - go figure), a very healthy eater (the mother - yes, interesting), the father who eats anything (even more interesting), a person who doesn't like spicy foods (me), and a person who hears the word "different" and wants to run.
Except for the very healthy eater (she never eats more than a half plate of anything anywhere), we rolled out of there.
Remember that there are "comfort foods" on there for your son. Your husband should really enjoy the salads (hint, combine two of the four dressings - excellent), there are enough vegetables on there for everyone, the chicken is very good in my opinion, and my husband loves the skirt steak (a bit too spicy for me).
We ate at Boma five times in one year. We got Boma-ed out.
