Warung Ursi is at number 65 on the Josephine Samson Greenstraat in Blauwgrond, at the quieter end of the street that also holds AJ's Indo foodhouse at 67, Warung Felicia at 99, Mirosso at 104 and Warung Renah at 106.
It has no website and no social page of its own. What it does have is a live listing on bestel.sr, a Surinamese ordering platform, which carries its address and telephone number and takes orders. Three separate sources agree on the house number.
No source anywhere publishes its opening hours, so we state none. The food listed on the ordering platform is saoto, bami, nasi, telo, tahoe lontong, sate, loempia and bakabana. No prices are published.
A Facebook page exists under this name but is auto-generated and marked unofficial, and the category it carries there is wrong. Do not treat it as the business speaking.
