We [almost] never eat out just for sustenance, for us it's more of an "event". So we always go to a sit down, table service restaurant, relax, talk, etc., and one that also has, at a minimum, __good__ beer (and sometimes wine).
Even when we were traveling over the last 30 days, in The Keys we ate out a good bit, but also cooked at the condo (mmm ... lobster tacos ...) and we were more recently in DC (fun and work), and we stayed in a executive type suite that had a small kitchen, so in the morning, we fixed breakfast in the room (scored some excellent smoked salmon and bagels from Trader Joes 3 blocks away). When I was doing my work thing, I just skipped lunch and ate a power/protein bar, worked through lunch time. Then in the evening, hit up an interesting restaurant in walking distance - or a couple of M stops away - where we could kill a good 2 hours just getting dinner. 🙂
I guess I should mention we also have the luxury of working from home, so we don't have to worry about dealing with a quick lunch from a cart or fast food joint, we do our own lunch at home 99% of the time, unless we're going out for some specific thing, like a school event where we pick up the little G and do like an early dinner.
