Situated mere steps from St. Isaac’s cathedral, Tandoor is about as far away from bland Russian food as you can get. For more than 20 years now they’ve been serving up real, authentic Indian fare and have won numerous "best restaurant" prizes for their efforts. They have all the usual favourites so you can try a couple and share amongst your buddies, whilst mopping up every last dollop of sauce with the thick naan bread. With two spacious rooms, this place is ideal for dining in large groups.
