Ok as everyone that actually ever ate here or read about dosas would know that this place has made it's way into the hall of fame for this cuisine so let's not get into the good as it's settled that food is great but let me tell me what to watch out for:
1. Make a reservation and try to come in small groups as otherwise you will be disappointed
2. Be very clear when you are ordering and ask the server to repeat if need be a few times to ensure no mistake - as with busy crowds and rush they tend to get the order mixed up - otherwise service is with a smile :)
3. In my opinion the lassi's were off - salty was too salty and sweet was too sweet and mango shake was more like mango juice
Finally tips to the owners to help solve wait problems
1. Get wireless buzzers / or give waiting guests tickets to know who came first as often parties that come late find a way to get accommodated and those that are patiently waiting tend to be forgotten
2. I think it's time to expand - literally your neighboring stores are dependent on your business and people waiting in line tend to go there to grab a snack! I'm certain you can negotiate a bigger place :)
