I visited Indian Chimney at approx 2.30pm on a Saturday - the busy rush was just dying down (as other reviews mentioned, the lunch is very busy until around 3pm, and restaurant staff said the same) so the host/manager (?) had time to deliver wonderful service, as well as stopping by our table for a chat. His English was very fluent, and his knowledge of vegan food great, which made ordering very easy, since the restaurant also serves meat. Vegan isn't specified on the menu, but there is a huge selection of vegetarian options, and as meals from the menu are made fresh, they are easily ordered vegan. The menu is huge - if you're travelling with omnis, it looks like there is no shortage of meat options either. Something for everyone!
I had the Dhal Tadka and Plain Roti, and shared Veg Samosas. Wonderful meal!! The dhal was, without a doubt, the best I've ever eaten (and I do eat a lot of Indian). I love spicy food, and this had the perfect amount of bite. The samosas and roti were also lovely, you can really taste how fresh the ingredients were in everything! The mango juice was great too. You do have to wait for the food to be cooked fresh, but it really isn't any longer than 5-10 minutes, and is more than worth the wait.
I hope to return during my time in Pattaya. I cannot rate the service and food highly enough! Definitely recommend.
