I like South Indian food and have been meaning to try this place but unfortunately the number listed on Yelp is incorrect.
Many unanswered phone calls later we decided to see if this place was for real and Yes it is.
Chennai Express is right next to Delhi palace on university drive.I think both restaurants are owned by the same person.
We walked in for lunch,the place was not very crowded we ordered at the counter and the food got to the table in 10 minutes which is great.
~South Indian Thali $9.95 (rice,sambar,rasam,three vegetables,papad and sweet curd)
~paneer Dosa $8.95 (crispy crepe stuffed with cottage cheese served with sambar and two varieties of chutney)
~Masala chaas $2.95 (spiced buttermilk)
The South Indian thali was filing and they gave me a masala dosa with it which was the high point for me.The paneer dosa and buttermilk were okay.
I also got some gulab jamun Yummy!
The staff is friendly and they have a $5 any dosa offer which is definitely hard to find in the valley.
PS I have posted a picture of their business card which has the Correct Number.
Cheers!
