Many years ago I took my wife to this restaurant. She didn't like Indian and I thought it was very good. Now she likes Indian and we went back and both liked it.
The strongest aspect of this restaurant is that all of the food has an excellent rich and unusual flavor. The naan bread is the best I ever had. It is also extremely inexpensive, about $7.00 for a weekday lunch buffet. It reminded me of the kind of old time authentic eatery you might find in Hong Kong that hasn't been remodeled in a century. In fact, the center it's in has the same look. To me, that was part of the charm. During our.lunch a "Maharaja on his day off" looking guy kept peeping in and out of the kitchen. More charm.
My fear is that this restaurant won't be around much longer, despite the fact that they've been around for 20 years that I know about. My suggestion would be to offer specials coordinated with nearby sporting events including transportation to and back in a gaudy bus. I would also offer a variety of heat levels for those of us so inclined. The buffet had no identifiable heat.
