Swagat is on the far west side of Madison. The restaurant itself is part of a new strip mall just off of Old Sauk Rd. The decor inside is nicer and newer than Maharaja's West and East side locations. The food is pretty much the same as Maharaja's. It's very, very good. The prices are about the same as well. The only thing I can really tell you is that if you are driving around Madison and you suddenly feel the need to have good Indian food you have three locations to choose from depending on your location.
Are you on the west side by West Towne mall? Go to Maharaja's on Odana Rd. Are you on the far west side by Old Sauk Rd? Go to Swagat's. Are you on the east side by East Towne mall? Well then go to Maharaja's on Thierer Rd.
Easy.
