This beautifully restored 300-year-old building was originally part of the Imamzadeh Seyyed Nasreddin shrine opposite before being separated when Khayyam St intervened. The Iranian fare (mainly kabab, chicken and fish) is well prepared and plentiful, though service is hit and miss. Still, for tea, water pipes and sweets (IR50,000) before or after an outing in the bazaar, it’s hard to beat.
