My go-to for chain coffee is Starbucks, but I've recently turned to Aroma.
Americanos here (or at least, at this location?) are strong and flavourful, with slight acidity. Haven't had any other espresso based drinks, since I do not like my coffee mixed with any milk or syrup.
For food, they have a lot of options, and lots of sweets. TRY THE BUREKA if you like savoury, buttery pastries. It's unarguably delicious.
NOTE: if you want a place to sit with your laptop, note that this location only has elec outlets along the wall with the booths, and these booths are very in-demand seats, making access very difficult.
