By T3 security at CUN, Maison Kayser is your French bakery stop before international departures. It sits airside in Terminal 3, so you’re fine on time if your boarding pass says T3. Expect classic bakery fare: croissants, baguette sandwiches, quiches, and pastries under glass, plus espresso-based drinks and basic soft drinks. Prices skew airport-high, but still under typical US hub levels for similar chains.
Maison Kayser in T3 usually opens early morning to catch the first wave of US flights; plan on coffee and a pastry around 6:00–7:00 if you’re on an early departure. Seating runs to small café tables right in the concourse, so you’re eating in full terminal traffic rather than in a separate dining room. Portion sizes on pastries and sandwiches line up with what you’d see at a city Maison Kayser in Mexico City or New York.
Figure on paying mid- to high-double digits in MXN for a cappuccino and around 150–250 MXN for a sandwich-and-pastry combo at T3’s Maison Kayser. Staff usually handles both sit-down and takeaway orders from the same counter, so factor in an extra 10–15 minutes at peak bank times before US and Canadian departures. If your gate is at the far end of T3, grab everything to go and eat within sight of the gate; it saves you one extra crowded walk back.
