I've eaten here about 5 times now, and have always had a stellar experience!
Food - 5/5 - I've had authentic Indian cuisine in India. This is not authentic, but definately brings in the flavors of India, with a familiar "American" feel. The Naan and Paneer are stellar.
Atmosphere - 5/5 - The designers really paid attention to the details. From the glass-wall see-through kithen, to the tile work and toe-open bathroom door, and the cool hand-sanitizing machine - it's all really well done!
Staff - 5/5 - Everyone at ChooLaah has been really polite and helpful thus far!
