As both a life-long vegetarian and Indian food junkie, I was so happy to find Masala right in down town Iowa City.
They have a terrific lunch buffet, usually with four or five main dishes, naan, side sauces and dessert. Their dishes are mostly quite mild, which is good for someone who is new to the cuisine. Mild, however, does not mean flavor-free! Everything I've had there (I go quite often) has been delicious. They have one of the best mango lassis I've tasted.
The space is not large; but it adds a coziness to the experience you won't find elsewhere.
Finally, the prices are great--you won't go broke eating at Masala!
