Joceline Lesso and Patric Lombo are set to open their new restaurant, Chez Biso, in Portland this Saturday, October 10, 2026. The 90-seat space will offer a diverse menu ranging from Central African specialties to familiar favorites.

Why it matters

The owners decided to launch the venture after catering clients encouraged them to open a permanent location. They identified a significant local scarcity of authentic Congolese and Central African cuisine in the area.

Chez Biso occupies the former site of Tokyo Sushi Ramen at 11 Brown St. The restaurant features a 90-seat capacity and will maintain daily operations from noon until 10 p.m.
