Chef Jeremy Duclut is converting the former Left Bank Bistro space in downtown St. Pete into Marcel, a French-inspired restaurant planned to open in September, per the operator's Instagram. The announcement names a chef directly, puts a concept behind a recognizable address, and signals that the corridor isn't losing its French identity — it's trading operators.

The roughly 25-dish menu at Marcel spans both French classics and some Mediterranean-leaning plates. Beef bourguignon and hanger steak frites anchor the French core; cacio e pepe, branzino, and grilled octopus extend the range. Crème brûlée closes the dessert list. The breadth suggests Duclut is positioning Marcel as a full-service dinner house rather than a tight bistro concept — a meaningful distinction for a room that will need to hold its own in a St. Pete dining market that has added significant competition over the past three years.

Duclut plans to launch with dinner service before expanding to brunch and lunch, a sequenced rollout common among chefs who want to stabilize the back of house before opening a second day part. The drinks program, per the Instagram post, will cover wines, champagne, and craft cocktails.

Left Bank Bistro occupied the space with a French-leaning identity, so Marcel's arrival carries a certain continuity of register even as the ownership and concept change. What the source does not yet confirm: the street address, a specific September date, or design and build-out credits. Those details will sharpen the picture as construction progresses through summer.

September is the announced target. Watch for a more specific opening window — and a brunch launch date — as Duclut moves through the build-out.
