Authentic delicious meals

Amazing variety of dishes, primarily vegan, with the option to add egg to some. The prices are very fair, and every dish we tried was packed with incredible seasoning. We enjoyed it so much that we came back for a second time. Can recommend the jungle curry, Tom Yum Thai Soup and Thai ice tea with coconut milk. 😋

Pros: Variety of dishes , Fair prices , Very friendly

This woman can cook!

This restaurant alone makes Kanchanaburi worth the visit. On is very sweet and her cooking is wonderful—best Tom Yum soup we’ve ever had!

After years of talking about it we found ourselves back in Kanchanaburi for the third time and finally took On’s cooking class. It was a lot of fun, very inspiring and great value for money—600 baht per person for three mains and a dessert, so between us we made eight different dishes! We got print-outs of the recipes to take with us and now we regularly make these dishes at home. It really has changed the way we approach Thai cooking!

Fantastic, tasty, healthy, inexpensive food

We loved the vegan food we got from On's. Favourites include the stir fried veggies with cashews, green curry and their icy drinks - cold hibiscus tea and peppermint lemon smoothie. We got enough food for two nights and took some back to our hotel room which had a fridge. Three orders of brown rice sufficed for two people for two dinners. Two dinners' worth of food cost less than our afternoon tea with an appie and two desserts at Kerree Tara (which had a nice ambience and nice view of the river and famous bridge). There is no AC in the restaurant so we chose take-out since it was a blistering hot day. We also had soup (can't recall the name but the one without coconut milk) that was out of this world. I recommend asking for mild spicing since we like some spice at home but 'mild' was just right for us. I also suggest you try morning glory greens. They are a bit chewy but not bitter and came with some other veggies and tofu.

Pros: excellent food, super healthy - lots of variety in vegetables, great value for money

Cons: no air conditioning

Went back again

It’s a BYO, they don’t sell alcohol there.

Yeah it’s good stuff, I had the watermelon smoothie, banana smoothie, spring rolls, pad see ew and red curry. All of it was delicious, although while I’m often okay with spice this had a bit more in it than I bargained for, went down to medium for the second meal, definitely go mild if you’re used to a medium in the west!

Pros: Fast service, Great variety, Good prices

Cons: Slightly too spicy (subjective)

Amazing food for amazing price

We were staying right beside so we came here a lot over our few days in Kanchanaburi. It’s a fully open kitchen so you can watch the chefs makes the food, it’s sooo cool watching Thai cooking. The food was amazing, really recommend their Khao Soi! It was insanely cheap for huge portions, they spoil you!

Pros: The open kitchen was so entertaining!, Best prices I’ve encountered in Thailand!, Super friendly service

Perfect for dinner in Kanchanaburi!

On's has a great menu with so many veggie options! There's only a couple that have egg and I believe all the shakes are vegan as they used coconut milk in the banana shake.
We also did the cooking class but it was a little rushed, but that meant we tried a lot of different dishes!
Our favourites were Khao Soi, Penang and the papaya salad. However we did order these dishes again and some came out too rich or too much garlic.
Overall, lucky to have this place in Kanchanaburi and it's really popular for anyone waking down the street.

Very popular restaurant for a reason

This place was a life-saver in Kanchanaburi. Other vegetarian restaurants are more Jay/buffet style and close in the early afternoon. Luckily, this place is still open at night so we went a couple of times. This allowed us to taste quite a large portion of the menu. All dishes are 80 baht with the exception of Khao Soi (100). Most dishes we tried were excellent! I would recommend to try the Pad See Ew, Sai Bua and Green/Panang curry. These dishes were our favorite. The pineapple fried rice and red curry were our least favorite options, although still good they tasted a little bit more basic. Also the mango sticky rice was somewhat disappointing regarding the syrup. But still this place is amazing and you can try a lot of great Thai food here. I do think it is a little bit weird that you have to write down your own order, service is also somewhat slow.

Pros: Amazing food, Friendly cooks, Affordable

Cons: Somewhat slow service

Some of the best food in Thailand!

We came here for dinner on our first night in Kanchanaburi and it was so good that we came every night after that! We tried all the curries, pineapple fried rice, curry fried rice, khao soi, pad see ew, and of course, Khao soi.

The food is made right in front of you and is packed full of veggies and tofu. Potions are generous and everything is soo flavorful. The family who owns the restaurant is very friendly as well.

Don’t miss this place!

Pros: Amazing flavors, Generous portions, Friendly staff

Good

It's hard to figure out which dishes are vegan, and unless you know some of the Thai language, it will be impossible to know for sure. I also did not get the rice that I ordered.

The food that did come was tasty and very filling. The price is also fairly good. I should not complain too much 😅

Pros: The taste of the food, The portion size

Cons: Staff speak very little English

Great everything

Despite being listed as a vegetarian restaurant it’s seems to be a fully vegan restaurant. Looked like everything on the menu was vegan.

The portion sizes are between moderate to large. I ordered three items and just barely couldn’t finish it.

Also a comfy, well lit, semi-outdoor setting. Food was tasty and quick. Women spoke decent English. Such good price for such a great experience. Don’t know what else I can ask for.

If that doesn’t:
Really tasty food, prepared right in front of you.
Big portions.
Many options on the menu.
Staff speaks good English and is really nice.

Pros: Staff is really nice, Tasty fresh food

Fusion Isaan food

Various vegan options. Pretty full during peak hours. The ingredients e.g. vegetables may not be conventionally local and may remind of Thai restaurant set-up in foreign countries. Delicious and homey service, however.

Pros: Vegan options, Spiciness level options, Homey and sincere
