Got to admit am not a big Sizzlers fan - the salad's good but the main dishes are pretty bland. Plus I'm usually full from salad by the time it arrives! Pattaya obviously has an abundance of farang-friendly restaurants.
Personal favourites include:
Simple Simon's in Jomtien
Pig and Whistle on Soi 7 (or is it 8?)
The Sportsman (off Second Road, South Pattaya)
