If you want a proper cocktail and some good food, with a view and a more upscale environment that the rest of Patong Beach, Joe's is a place you must try. Every trip to Patong I have dinner and drinks there at least one time. Make your reservations for 6 pm for the 6:30 sunset.
The pulled pork and chips is amazing, so is the crab cake. Also the bar selection is so much better than most of Patong's bars. Dress nice, have a nice night out.
