We didn’t love this island or its food, unfortunately. Because its raison d’etre is tourism, the food is all overpriced and not too authentic – even more so than on Koh Phangan. The food quality was better than on Railay, I thought, but the prices were worse. Here’s where we ate:

• Paradise Pearl Restaurant [Long Beach]: This was a nice location, right on the beach, with a breeze and our feet in the sand. (Watch out for sand mites! They bite.) We had some delicious and only mildly over-priced fruit shakes here: I even ordered two! My cousin L and her boyfriend E got this fried fish dish and a shrimp thing. B and I had curries, as usual. All of them were pretty decent; we didn’t return mostly because it wasn’t near where we were staying. 
• Pirates House Restaurant [Tonsai Village]: I ate here because I couldn’t find anywhere else that had a non-American breakfast (eggs, toast, sausage). It was a twenty-five minute walk from our place, if that gives you any indication of how long that took. The curry I ordered here was not good. It tasted like it came from a container, and it was a very unnatural color. My shake was better and the staff was very nice, so I cut them some slack. But don’t order a curry.
• Lemongrass Restaurant [Tonsai Village]: This was another accidental discovery, but it turned out much better. B was waiting at the pier with our bags, but I hadn’t had breakfast, so I ducked in here to hoover down some food before our departure. I pretty much inhaled the cooked vegetables and chicken I ordered, along with my mango shake. As other reviewers note, the staff was incredibly nice – and likely confused by my speed eating performance. Bonus: it wasn’t super overpriced. If this hadn’t been during my last ten minutes on the island, I definitely would have returned. Recommended!
• Hippies Bar/Restaurant [Tonsai Village]: As I described elsewhere, this was more of an entertainment experience than a dinner. Our food was fine, but the fun was the guitar-playing, the location on the beach, and especially the fire dancing show – that B participated in! Though hokey, it was lots of fun. If not here, you should check out something like this on the island. 
• View Restaurant [Tonsai Village]: I don’t know the name of this restaurant with a view, but it was nice. Expensive, mind you, but the breeze and view over the water was relaxing. I believe I ordered a tom sam salad, and I can’t recall what B had, though I believe it had pork in it. Here was the view from one side:
• Internet Restaurant [Tonsai Village]: We grabbed lunch at a restaurant with strong wifi in Tonsai, a bit closer to town than our view restaurant. All I remember is ordering too much food, including veggies for me. It wasn’t amazing, but the internet access was worth it.
• Ice Cream Stand [Tonsai Village]: B got an ice cream from a guy who made it out of ingredients that he folded on a crepe-making platter. He folded in mix-ins, and it was fun to watch, though – to be honest – it didn’t look as amazing to taste. B liked it though!
