It has the aura of a fine restaurant...and the prices to match, at least by US standards, but I didn't find the food very exciting. They were running a weekend special of as many trips as you like for 32 CHF, and on my second trip I didn't find myself interested in much. The Dal was bland and the curries overly salty. On the upside, the range of foods was a lot broader than most US Indian buffets, with a good range of salad bar items, plain cooked spinach, and other miscellaneous foods.
As Lola mentioned, the pricing structure is unusual, so be sure you understand it and fill your plate accordingly to take full advantage of what you pay!
