I couldn't tell if it's spices or bathroom smells (or both!), but they could use some better ventilation here. The restaurant is small and unassuming; decor/atmosphere simple and functional.
Had the Chicken Tikka Masala and Goat Karahi, with rice of course. The goat was overly tough by my standards, but the sauce was alright. The spices were clearly visible and had nice chunks of ginger in it. The Chicken Tikka Masala felt fairly standard, with the chicken being on the dry side.
Bottom line: Not the greatest, but works in a jiff if you're super hungry. Oh, if you order water, they'll give you bottled water. Specify if you want (free) iced water.
