That said . . . as you (probably) know (but if you don't, you're about to find out), poly relationships have all kinds of (sometimes incredibly arbitrary but also incredibly important) rules. If one of their rules is "My wife doesn't want to hear from or about my girlfriend," TWO, then your restaurant recommendations are going to fall flat. Being poly means navigating rules (and sometimes asking to renegotiate those rules) and juggling multiple people's feelings, needs, and concerns. You have to show respect for their rules, TWO, as they are each other's primary partners. But your boyfriend and his wife have to show respect for you too. Secondary though you may be, your needs, concerns, feelings, etc., have to be taken into consideration. And if their rules make you feel disrespected, unvalued, or too low on the hierarchical poly totem pole, you should dump them.
