Joe, the best restaurant in Pattaya is (arguably of course) Cafe des Amis. It is superb.
I've been numerous times and never had anything which was not scrumptious.
Cheap it's not, but hey, you don't have to go every night!

(Needless to say, pay no attention whatsoever to MickP's two cents as he has never been to any of his suggestions. Can I say "dehydrated noodle bucket" lunch at 7-11.)

Also, regarding Sunnee and Jomtien Complex: things have really changed with both. Sunnee is darker and quieter now with quite a number of bars closed. A bit of a morgue, though certainly still a going concern for some guys, though its noticeably downhill.
Jomtien has gone in the other direction . . . lots of new bars, lots of noise and fun going on. So much more vibrant than 3 or 4 years ago. You can't help but enjoy an evening there.
