Overview

Lilac Labs builds conversational AI agents that handle drive-thru orders at quick service restaurants. The system listens to customers, understands menu items and modifiers, confirms the order, and passes it directly to the kitchen point-of-sale, freeing staff to focus on food prep and guest experience. Designed for the noisy realities of drive-thru lanes, the assistant manages upsells, promotions, and complex customizations while keeping conversations natural. Operators get analytics on order accuracy, throughput, and average handle time, with human fallback for edge cases that require staff intervention.

Use it every day

Honestly didn't expect to like it this much. Order accuracy and performance analytics is exactly what I needed, and speeds up drive-thru throughput. I do wish limited to QSR drive-thru use cases, but I reach for it almost every day now and it just clicks.

Compared a few options

Evaluated this against two competitors. Where it wins: human handoff for complex requests and consistent upselling on every order. On balance the feature set — especially human handoff for complex requests — justifies the 5 stars for our use case.

I've evaluated a lot of these over the years. What stands out here is pOS and kitchen system integration — handled better than most — and reduces labor pressure on front-line staff. Worth the time if this is your use case.
