About the only place you could eat with a dog would be an establishment with an out-side picnic area, not too difficult to find in the summer time. Personally I've brought my dog many times to Red Hill Dairy in Center Harbor (outside tables.) Legal seeing eye dogs can go anywhere however I'm sure that's not your case. I get a kick out of the Wal Mart near me in Mass, they have a sign on the door that "service Animals" are welcome.....They do not have a choice, it's the law! A little P.R. I guess.
I do keep Hunter close to me, he's a 75 lb Weimeraner and the biggest baby alive. However I suppose if you didn't know him he can be intimadating (SP??) looking. Oh, want a friend for life?? He loves ice cream!
