Mc Donald's

Right by T1 check-in, Mc Donald's covers the 3 a.m. hunger.

This stand-alone Mc Donald's sits pre-security in Terminal T1, handy if you are meeting someone or arriving by car. It is outside the boarding area, so you cannot reach it between connections without exiting and re-clearing security. If you want a known quantity before a 10-hour overnight to Europe or a regional hop, this is the predictable fast-food stop.

Hours run 24/7 except Tuesdays, when it reportedly closes around 00:00, so late-night Monday flyers should plan around that gap. Early departures at 05:00 and midnight arrivals from São Paulo or Buenos Aires still hit the golden arches most days. Staff shift changes tend to show around typical meal peaks (13:00 and 21:00), so waits can stretch a bit then.

Price tier sits firmly at $ by Uruguayan airport standards, so a combo lands near local street pricing, not boutique terminal markups. Expect the usual McNuggets, Big Mac, and chicken sandwiches, plus fries that taste the same in Montevideo as in Miami. Portion sizes stay US-style, not shrunk to tapas levels, which can save you from paying twice for snacks in the same 6-hour window.

Since it is pre-security, this is more useful before check-in than during boarding calls. If you show up 2 hours before a LATAM or Aerolíneas Argentinas flight, you can eat here, then clear security, then head straight to the gate in T1 without hunting for more food options. Lines usually beat the ones for last-minute sandwiches airside, especially outside the 19:00–21:00 wave of departures.

Tip: if your flight leaves after 23:00 on a Monday night rolling into Tuesday, grab food here before 23:30 in case that “excepto martes hasta las 00:00” shutdown hits right when you get hungry.
