in no particular order:
Papa Johns: still excellent food- beef in cognac sauce

bams bams- cheap as chips but nothing special.
sara janes- first time ordered panang curry with rice- 20 minutes between rice arriving and then the curry. family enjoyed their food so decided to give it a 2nd try. food arived together and was delicious.
jasmines- absolute quality
nesadarami ? (oposite jasmine) lovely.
colins fish bar (near Chinese temple side of hilton beach) best fish and chips ever!!
mini farm- worth the effort to get there.
catalina- bland mexican but plenty
crawfords- nice but pricey for what you get.
little italians next to coffee world opposite police station- tremendous pasta.
mp guest house- liitle street up from the hilton- best scrambled eggs with coffee for 30 baht- massive bowl of musli and fresh fruit for 50 baht.
Indian- marahaja?? top food but watch out they pour you water when you arrive then charge you- its not the price but the practice that p"£$£D me off, also the only place i ate that charged a service fee. i always tip 20% but not here due to this.
siam (next to sara janes) nice food but service iffy if its busy.
left the best till last although i should not tell you

go to the beach between hilton and sofitel, turn left at the beach entrance, 50yds to the beach shack with the red and white poles (approx 4 lads will offer you sunbeds)
cashew chicken or hot fried sauce with prawns, i swear you will not have better anywhere in the world.
enjoy Hua hin, it is a wonderful place although i can see it getting alot busy. i have been to loads of places in thailand with my family- they all have the plus points but hua hin has everything you need and is extremely chilled out
