Chimney Fresh is still fairly young so there's some problems. Service is very slow so bear in mind when you come you will have to wait a minimum of 10-15 minutes for someone to take your order. There's two waitresses usually but apparently they can only handle one table at a time. We have been the third table a couple times and this seems to cause service to slow to a crawl.
Also, many items on the menu don't seem to be available with no explanation given. One day we can order a cheese Dosa, another day they just won't make one. It doesn't really make any sense.
The food itself is pretty high quality though so it's worth coming at least once. The hours are unreliable though, the owners will close if they feel they don't have business during the listed business hours so it's hard to know if they are just not answering their phone or if they have closed.
Also, there is a problem with communication with the servers in that, even repeating the same order multiple times, you're never sure if they actually understood. Your order has a decent chance of getting messed up.
Overall, it's a nice place that needs some crucial improvements but everyone is friendly and the food is great for a fair price. It's worth a try but it can be a bit of a frustrating experience.
