Can try a few there's Caffe Ritazza is wholly owned by Compass
Group, T1 Departure/Check-In Hall East open 24hrs. They offer great
Ritazza coffee and a delicious range of unique, hot
sandwiches.
Swenson's fusion ice-cream sundaes, cakes and food menu T1 Viewing
Mall West or T2 Departure/Check-In Hall .
There's also the usual Starbucks, Coffee Bean, Fusion Smoothie
Cafe, Delifrance...etc
If all fails, try the Super Multi Vending Machine at T1 Arrival
East. These usual machines dispensing cans of soft drinks, candy
bars, noodles, chips and for dessert a cream roll and even a can of
Bird's Nest drink a complete day's meal.
Have fun at the airport!
