For a drive-thru area, I’d go with a heavy-duty commercial outdoor trash bin in the 40–50 gallon range, not a lightweight open-top can. Look for a domed or hooded top with a push flap or a restricted opening, because that helps keep cups, wrappers, and napkins from blowing out and makes the bin less attractive to pests. A powder-coated steel body or a concrete base is a good choice for an urban setting where the bin may get bumped, rained on, and exposed to food grease.
I’d also want a rigid leak-resistant liner, a bag retainer ring, and a smooth interior so staff can empty it quickly. If the drive-thru gets very busy, a rectangular steel bin with a small hooded opening is usually easier to service than a decorative round can. Make sure it is bolted to a concrete island or pad, placed outside the vehicle clearance zone, and emptied often enough that it never overflows. In short: a covered, anchored, commercial-grade bin with a restricted opening and a rigid liner is the one that works well in a drive-thru area.
